Outlook and Gmail's Less Secure Apps Setting

› Outlook › Outlook and Gmail’s Less Secure Apps Setting

Last reviewed on May 2, 2025     113 Comments

Upcoming Gmail changes

Google Workspace accounts had “allow less secure apps” turned off May 1 2024. This was turned off on consumer accounts at the end of May 2022.

Users with Outlook 2016 (retail version), 2019, 2021, and 365 won't have a problem when Less Secure Apps is disabled. They can connect to Gmail accounts (using IMAP) with Allow less secure apps turned off. Gmail users with older versions of Outlook who want to continue to use Outlook will have two options: upgrade to new version of Office or enable two step verification on their account and use an app password.

At this time, adding a Gmail account to Outlook as POP will require the user to enable two-step verification and use an app password to log in. Newer versions of Outlook will need to use app passwords with POP accounts too.

To enable two-step verification and get an app password, log into your Google account and open the Security settings.

It is highly recommended that you use two step verification even if you are using a supported version of Outlook!

If you are unable to enable two-step verification and upgrading Office is not in the cards, you’ll need to use a different email client or use Gmail.com. (I recommend eM client as a good Outlook replacement.)

Error Messages

Task 'user@gmail.com - Receiving' reported error (0x800CCC92): 'Your email server rejected your login. Verify your username and password for this account in Account Settings. The server responded: -ERR [AUTH] Username and password not accepted."

If you have the account added as POP and receive this error, you need to use an app password to sign in. If you do not have two-step verification enabled, you will need to enable it to create an app password.

Two-Step Verification

Older versions of Outlook can't connect to Gmail servers unless you also enable two-factor authorization then use an app password in Outlook. (The app password is a one-time use password that can be voided if you suspect it is compromised, without affecting your “real” password.)

To check or change your settings, sign in to Gmail then open your Google account settings.

If you enable two-factor authentication, you'll create new app passwords at App passwords. Gmail allows you to revoke individual app passwords, which you can do by clicking the trash can icon to the right of the device name.
create or revoke app passwords

In my experience with Gmail, their implementation of two-factor authorization is not annoying at all and retains the authorization. It doesn't request re-authorization often, which makes using an app password fairly painless. If you use public hotspots, you should enable two-factor.

Add an App Password video

Please note: the email address shown in the video is used only for testing and screenshots. I will not reply to email sent to it.

While the YouTube video below was recorded using Outlook from Office 365, the steps are basically the same for all versions. I have a recording made using Outlook 2007 here.

    Hi Diane,

    I am able to use the Goggle App Password to add my gmail account to Outlook (Microsoft 365 MSO (Version 2301 Build 16.0.16026.20002) 64-bit). It even indicates that it has connected successfully and sends out a test email that I receive. However when I try to actually send/receive or sync within Outlook I am prompted to authenticate again and after entering my gmail account and selecting next I receive a message "This browser or app may not be secure. Try using another browser....". Any ideas?

        Not sure which version, apart from its (pwa) but cant find more info than that. Its part of Microsoft 365 but obviously a newer version because its different to the version i use on another machine.
        The gmail comes in fine on gmail account. I can send from outlook and it shows as sent mail and receives on gmail but not on the laptop its sent from.
        I also get a message from Microsoft saying That Microsoft account doesn't exist, Enter a different account or get a new one. Even though i am signed into the gmail account...

      When you use IMAP, it is email-only - you need a 3rd party utility to sync calendar & contacts with a Gmail account - companionlink or gsyncit are two of the best.

    Hi Diane - I have similar issues to Greg. It seems my settings have been affected by Google's May 31st changes that affect security/login. Coincidentally, my computer crashed 5/17 and it was in data recovery until 6/14. Since I have had my computer back with a newly installed OS, I have not been successful in setting up my Outlook 2019 desktop client again. I have my existing PST file with 6 gmail accounts I funnel in via POP3 (yes, I still have my reasons/preference for POP3). I know I am using the exact same settings that were in place prior to the crash on 5/17 because I keep screen prints of my account settings. So, I am convinced that Google's security change has something to do with why I cannot connect. The only difference is that I previously had my Outlook 2019 installed on Windows 10 and it is now installed on Windows 11, but I don't see how that would affect the mail clients. I get the same issues with login passwords and being unable to connect to the incoming email gmail server. Would this require the 2FA app password generation? I am desperate to get this working. I have researched the internet tirelessly and worked with a Best Buy Geek Squad tech to no avail. Please help!!!

    Thanks!!! you're a life saver, managed to get Gmail working again on Outlook 365 desktop client. I'm disappointed that Google did not notify Gmail account users who access their accounts via third party apps like Outlook, that they were going to impose stricter security measures which might affect their current access after 31 May. Furthermore, they should have provided possible solutions to maintain access if users are affected, i.e. similar to what you have done. FYI - I use Gmail PoP access, setup 2FA in Google, generated an app password and used it with my email address in Outlook to regain access :)

        With Gmail POP accounts, you need to use 2-step and an app password in outlook.

        Have you used the account as POp before? You need to enable POP in gmail settings.

      If you are using a POP account, you need to enable 2-step verification and then get an app password to use in outlook in place of your regular password.

      Or remove the pop account and add it back using auto account setup - this will add it as an IMAP account and it will work without enabling 2-step.

      • Diane Poremsky says

        June 18, 2022 at 1:37 pm

        If the account is in as IMAP, it should just work. If it won't you need to enable 2-step verification.

        Which version and build of Outlook are you using? See File, Office Account for the information.

      • Greg says

        June 18, 2022 at 4:30 pm

        It is V2205
        build 16.015225.2078 64 bit

        if i have to do 2 step verification, what are the steps if I already have IMAP?

      • Diane Poremsky says

        June 19, 2022 at 12:28 am

        If you enable 2step, you will just need to verify after you enter your password - but Outlook 2019 uses oAuth2 and does not need to use 2step for IMAP accounts (it needs it for pop). I tested it with the same build you have - IMAP does not need 2step or an app password - so something else is wrong.

        You could remove the account from outlook then add it back - but if you have calendar & contacts in the gmail data file, in folders named 'this computer only' you need to export them first.

      • Greg says

        June 21, 2022 at 6:52 pm

        I deleted the account and have tried to reinstate it. It keeps telling me that I to check my password. I have checked that numerous times. I can't figure out what it could be.

      • Diane Poremsky says

        June 21, 2022 at 10:23 pm

        Are you adding it as POP or IMAP?
        Do you have 2-step verification enabled?

        Depending on your outlook version, you will need two step enabled and will need to use an app password in outlook instead of your real password.

      • Greg says

        June 22, 2022 at 9:16 am

        i am using IMAP. 2 step verification is off. should i turn it on and follow your instructions for 2 step in your video for POP account? It keeps saying wrong password, can't connect to server.

      • Diane Poremsky says

        June 22, 2022 at 11:09 am

        Yes, if it says wrong password, enable 2-step. It's required for Outlook 2013 and older - but updated versions of Outlook 2016 and newer should work without 2-step on.

    Thank you very much Diane. I have been cracking my head over this issue with my Outlook 2013. Trying to delete receiving mails with MFCMAPI, checking all the setups, and trying all solutions available but none helped, until I saw your resolution. It did resolved the issue with the Two-Step Verification and creating an App Password. However, the password to input in Outlook do not permit copy & paste. No worries - have to type in manually without any SPACES.

I'm an old techie (used to install IP Telephony under the H.323 protocol...yes very old). Now if I could just figure out why Google still shows me at 12.7gb of usage, both before and after I deleted several gigs of data from my account...hmmm.

    Hi Diane.. I just wanted to say thank you so much for your advice. Taking it has enabled me to continue using my Outlook Express 6 email client after Google/gmail took action on third party apps.. and yes I did say.. Outlook Express 6!

    Over the years I've tried many email programme's, but always ended up going back to Outlook Express because I felt comfortable with it, and it does what I require admirably. I was therefore more than a little irked when Google decided to deprive me of its use after May 30th 2022. Now, thanks to you its up and running again. So pleased..

I don't like built-in obsolescence & hate forced upgrades! I also have spent way too many hrs looking for a work-around to the no-longer-allowing less secure apps mess. My Outlook is IMAP, configured, I've confirmed email acct settings, set up the 2-step auth. Nothing works. Do you have a video working with 2003 with IMAP?

I use Outlook 365 desktop to access 2 Exchange accounts and 5 Gmail POPs... which I continue to use since IMAP inboxes are not unified on desktop, so sticking with POP until someone figures that out.

    I've been dreading the sunset of "less secure app" access in Google, but it's been impossible to find the correct steps to remedy it. However, setting up 2FA and an "App Password" for each Google account, then creating the Google-generated password in Outlook (replacing your original password) works great. As you note, it's pretty painless and seems to be a one-and-done (so far).

    Someone posted a step-by-step that is very helpful.

      If you are vigilant (since there are no more security updates), you can get more than 2 years out of 2013. :) A lot of people are still on 2010 and there are more than a few still on 2007.

      You need to use an app password with POP accounts - in all versions of Outlook - as they won't ask for the second factor.

    I created an app password for my google account. I then changed my password in Outlook 2007 in accounts ( I know it's old but it's been working fine until yesterday) but I continue to get the error message above 'Your email server rejected your login. Verify your username and password for this account in Account Settings. Is there something I'm missing? I am using the settings provided by gmail for POP3 and IMAP but can't get either one to receive messages. I'd appreciate any suggestions to get my Outlook working again.
    Also can you provide me the correct settings for incoming and outgoing servers in POP3 and IMAP as maybe I am using incorrect settings.
    Thanks

      use pop.gmail.com, port 995/SSL and smtp.gmail.com port 465/SSL - authenticate outbound mail using incoming password.

      Did you copy and paste the app password into the password field in Outlook 2007? This insures you get the password correct.

        Thanks for your response. Unfortunately the Outlook accounts dialog box to enter new password does not permit paste so I had to type it in. I checked internet and typed app password with no spaces (also tried with spaces) but neither option worked. Any other suggestions? I am about to throw in the towel and just use gmail instead of paying $150 for a newer version of Outlook. What do you think?

        Hi Diane,
        After many many hours and your incredible help I was finally able to get the darn thing working. I had to generate a second app password as I think the first one was not properly registered with Google for some reason. With the new app password and a new Outlook profile I pasted the app password into the dialog box that kept popping up and it finally accepted my logon. Thank you again so much. I was getting used to gmail but I really prefer Outlook.

        Hi Diane,
        It's me again. Outlook stopped working the next time I tried it. I had to create yet another app password. Furthermore I lost all the mail in all my folders. I tried importing from the pst file but it says that that data already exists in the current profile. Can you tell me how to get back my emails as the pst file exists in my c drive. Thanks so much.

      • Diane Poremsky says

        June 12, 2022 at 11:36 pm

        Which version and build of Outlook are you using?

        You won't lose email - if you use a POP account, the mail is in a pst file on your hard drive. If you use imap, its on the gmail server and will re-sync. At most, you could lose your calendar and contacts if they are in a folder named 'this computer only'

        Don't import the pst - if you use imap, its on the server (it might be in the All Mail folder is you switched from POP to imap), if you use POP, just open the pst file.

        You need to create the app password in google.com then paste it into the password field in Outlook.

        By Outlook 7 does you mean outlook 2007? I have this video I recorded for another user that shows how to do it.

I've been searching for a while, finding bit of info that made sense, but your article pulled away the fog.

    This confirms what I did last week. I should have known you would solve this, apparently several years ago at that. Over the years I have used several of your solutions. Just must remember that when the next problem arises.

    I'm hanging on to a legacy app that supports no later than Outlook 2010. (I know, not a great plan.) Google sent me the email re "On May 30, you may lose access to apps ...." (Looking back at the Learn More link in their email, I see they did include using an App password as a possible solution, but I didn't understand it at the time.)

    My first thought was disconnect outlook from gmail, keep outlook connected to the non-gmail address I use, and set gmail to forward all of its email to my other address. Then somehow I stumbled upon the app password solution myself and, lo and behold, it works just as you say. This solution also avoids changing any outlook settings (other than the password). Thanks again. harris maynord

    I am using Outlook2016 because I can see several my e-mail boxes in the same application and also archive it locally. It also allows to use MS calendar, and embed pictures and text in different fonts from other MS Office applications. Google tools (eg browser based mail client) displays mails incorrectly and does not allow multiple accounts in common mailbox. My connection is POP3 and it stopped working today, and then appears to be working again after 12 hours.
    I do not want to upgrade to new office (as it is not free) and I don't want other mail client. It is *MY* mailbox and I am OK to make a decision to live with "less secure mailbox", specifically because there is no explanation why Google thinks that this application is less secure.

    I also saw the note of "app password" - for some it is intuitive, but I need better explanation what it is, how it works with the mail client, and why exactly Google thinks that it is more secure. The name "app password" does not tell me anything meaningful. Could someone explain what it is and how it works?

    On the side note: Google lists only "IOS" and Android on their tech support page, they probably think that Windows does not exist in their world?

      Is your account working now, with POP? My gmail pop account is not working with my regular password.

      An app password is a single-use password (16 characters) you need to use when the application you need to log into doesn't properly support two step authentications, so you can't log in with your real password and answer the second verification.

      Because POP protocol in Outlook does not yet support oAuth2, it won't ask for the second verification - so you need the app password.

      You shouldn't need an app password with 2021 - unless you have the account added as POP3. It doesn't yet support oAuth2 yet.

    Kindly reply point wise

    1) Can you explain in simple steps considering less secure apps is closed by google now then what to do to ensure outlook still works.

    2) If 2 step authentication is enabled in admin i guess even if less secure apps is closed by google still outlook works fine. As per above article only one time app password to enter in outlook and thats it continue to use.

    In this case how to generate one time app password. Please give simple steps.

    3) Also finally OAuth 2.0 is all difficult and cant really understand steps. Can u tell me in simple step by step how to authenticate users using OAuth 2.0 once less secure apps is disabled by google.

    4) Once less secure apps is disabled by google can 2 factor authentication enable be done to ensure if any user is still not able to use outlook he can use it.

    5) I believe that once google discontinue less secure apps if 2 step authentication is enabled and forced and users have done steps then it wont affect their outlook please confirm this or clarify if i am wrong

      "No need to do this..." ... what this ?
      I have a Gmail-imap account in Outlook 365.
      Today I try to pass my Gmail account from "Less Secure" to "Secure".
      You can´t avoid 2 steps:
      First implement 2-Step Validation, receiving a message in smartphone when you sign in Gmail.
      Second and only after that first step, get a 16 digits code to change your PW in Outlook/Gmail.

      It's such a confusing procedure and forcing 2 validation steps, that I, like most users, have returned to the "less secure" gmail account.

      If you know a simple way of having a "secure" account Gmail-Imap in Outlook, please tell us.

        Those are the choices: less secure or two step. Depending on your outlook version, it will either ask for the 2nd step or you need to use an app password. In my experience, gmail is pretty good with 2-step - once the account is set up, you don't need to respond with the second factor or reenter the app password. On the other hand, less secure isn't that much less secure, especially if you don't use public wifi.
