Username & password rejected by pop.gmail.com server

I have created a new Gmail account which I can access via the web, but when I ask Tbird (52.9.1 (32-bit) to collect mail from the new account, pop.gmail.com responds "Username & password not accepted". This new account name has this format: xx.xxxxxxxxx.xxxxxxx@gmail.com and I am wondering if the two periods in the name may have some bearing on my problem. I have created an 16-letter app password and replaced my original password, but that did not make any difference. Tbird tries to send the username & password, but the pop.gmail.com server still won't accept them. All my other Tbird accounts work fine with their respective app passwords. Hoping someone can help me find a solution to this strange occurence. Thanks for helping!

Chosen solution

The article states that the 90 day restriction only applies if you allow access by 'less-secure apps'. Even then, the restriction may not always be applied. But that isn't necessary if you set the authentication on the incoming and outgoing to OAuth2, the recommended method for gmail, Yahoo, AOL. Of course, that's not possible with TB 52, so you will either have to wait for 90 days, or perhaps find that the restriction is no longer imposed.

You will find increasing security restrictions as time goes on with Windows XP. Even IE11 on Windows 7 will be blocked from accessing gmail after March 15 2021.

Unfortunately, TB 52 doesn't support OAuth2 authentication, which is the method currently recommended for gmail accounts. Did you allow access by 'less-secure apps' in the Google account settings?

Hello sfhowes!

Thanks for your reply and the reference http://kb.mozillazine.org/Using_Gmail_with_Thunderbird_and_Mozilla_Suite.

There were many options included in that reference, the one that I noted specially was that Gmail does not allow access to new accounts less than 3 months from email clients (like Tbird). The new account I opened was created on January 16, 2021 . So that may possibly be the reason my Tbird is unable to make a connection to download. The other information did not seem germane.

All my other Gmail accounts which Tbird connects to have 16-digit app passwords and work just fine. It's only the new account that is not able to connect.

I'm going to have to get to that new account directly via web access to Gmail for the time being, until the 3 month lifespan is accomplished before asking Tbird to do it along with my other accounts.

Thanks for your help.
