I am trying to read my gmail email using Thunderbird. However, once I fill in the server configuration, I get a 2fa pop-up window with an error message. See attached.

What can I do to get this to work? Or is Thunderbird unable to access gmail?

Thanks in advance, Mike.

I can get to the "stored passwords" box, but the email I need to change the password for isn't listed there. I have tried to send and receive messages but nothing makes a "enter your password" box pop up. All I get when it tries to retrieve messages from Gmail is a box to give my email, (just that, not a password) and then an error message that it won't work and there is no more information. I'm using Linux. I've had both this particular email address (as well as others) and Thunderbird for years, perhaps two decades, and I can't figure out what to do now. I was going to change all my email passwords for security reasons, but there's no way I can do that until I can get Thunderbird working with POP access again. Thank you.

After installing upgrade to 139.0.2, POP downloads failed. Last was on 6/19/2025 at 8:19PM. I deleted both saved passwords.. Went to AOL and generated a new APP password but there was no way to upgrade to it. I sent a test message to myself [ smtp] and AOL logged me in and TB generated the saved password oauth://login.aol.com (mail-w).

However even with shutdown TB and restart, there was no request for a POP password [ such as the new AOL APP generated one. What should I do? Is this a bug? I can read and use AOL mail on my browser [EDGE]. LKint@verizon.net

I changed my Google account password just today. I have used Thunderbird on PC for Gmail without issues for years. I went into Thunderbird Saved Passwords and changed the appropriate line to the new Gmail password. I restarted Thunderbird and tried to send a test e-mail. I kept getting "Login to account Google Mail failed" with a box of 3 options, Retry, Enter New Password or Cancel. When I click on either Retry or Enter New Password, it doesn't give me a chance to enter a password and goes immediately into the same "Login to account Google Mail failed" box with the 3 options. I searched and read the support and one of the option is to remove the line from Saved Passwords and re-create it. I did that and tried to send another test e-mail. Now I'm still not getting a chance to enter a new password. I keep getting the box with the 3 options which doesn't allow me to enter a new password. There isn't a new entry in the Saved Passwords.

Strange thing is Thunderbird is receiving new e-mails fine. I'm just not able to send.

Thanks.

Can't install yandex.ru mailbox to Firefox for Android. Using generated stecial application password did not get s result anyway

This morning, Thunderbird asked me to sign in to my two gmail accounts. Why, I have no idea. Later, I wrote an e-mail in my cjbbrussels@gmail.com account, but it won't send.

It looks like the password is incorrect. I'm not sure how to correct it.

Please help.

There are many sites where I am unable to log in. One of these three things usually happens. 1. Fill out email and password, click log in, infinite loading with on some sites (like Spotify) an error about not being able to load. 2. Fill out email and password or the form, try to click send/continue/log in but I can not click it, it's greyed out. 3. Fill out email and password, get told it is incorrect. For any of these issues, if I switch to chrome (which I am trying to avoid) it works, it's just limited to Firefox.

I have tried disabling the advanced protection, that doesn't change anything. Any tips would be much appreciated and I will try to answer any questions as fast as possible.

Thanks in advance

I apologize in advance for the language, I'm writing from a translator. Thunderbird on several accounts, every few days requires a password ... "login to the server failed, enter a new password". Just in case, I changed the passwords on these accounts (with the option to remember), a few days of peace and again the problem. However, logging in with the old passwords before and the new ones now on the server is no problem at all.

I reinstalled TB but unfortunately it doesn't help. The same on the stationary and laptop, what could be the problem? Currently, email is available only on the server, I do not have access to Thunderbird.

After installing latest Thunderbird, I attempted to set up to shadow the existing ATT account which is currently monitored via IMAP on both the web site and my iPhone (in hopes of replacing the web site). The automatic setup option ONLY showed the old POP account which I used years ago on the same email address ([edited] @att.net), so I went to manual configuration, where the default was POP but a dropdown list allowed me to select IMAP. The first attempt was no good, so I checked the settings for Mail on my iPhone (the ATT web site did not display any configuration at all). The hostname was shown as imap.mail.att.net, port 993, security was SSL (I selected SSL/TLS), the auth method was password, and my username was my email address. on the outgoing server, the iPhone had smtp.mail.att.net, port 465, which I copied, SSL/TLS, password, and my email address as username. the Re-test button also found those same settings (green message box).

But the Done button, after a short delay, replied "Unable to log in at server. Probably wrong configuration, username or password." in a yellow message box.

I cannot get any further than this, and have no idea where to turn. Both the iPhone and the web site on Windows 10 still work, with the same password (which I copied for the mail signin, so I assume that is the password which was submitted to the servers, since there was no place to enter any other passwords.

TB keeps asking for my iCloud calendar and contacts username and pw. I enter both, using my iCloud app-specific pw, but they are not accepted. Any help much appreciated.
