Thunderbird seems to have replaced my login password for comcast.net with a bogus, several hundred character long password.

I have been using Thunderbird for several years to read and send my Comcast.net email. As of 5/23/26 Thunderbird is no longer showing my new emails. However, when I login directly to my Comcast.net email account their are plenty of new emails.

I thought that perhaps Thunderbird is using the wrong password to try to get my comcast.net email. So I examined my password by going to Menu > Settings > Privacy & Security > Saved Passwords , which opens the "saved logins" window. Then I pressed "show passwords." I found that instead of showing my usual comcast.net password, it showed something that is bogus and several hundred characters long. I right clicked on the bogus password, selected "edit password" and entered my usual correct password. The "saved logins" window then showed the correct password. Finally I closed the "saved logins" window.

Then I opened the "saved logins" window again and confirmed that the password was still correct.

Then I exited Thunderbird and restarted it. Usually, when I start Thunderbird it simply opens my inbox window and shows me my new emails. But now a separate browser window opened from xfinity (comcast) showing my email account name and asking me to sign in. I pressed the "Let's Go" button and is prompted me for my password to the comcast.net account, which I entered. This password was entered in a browser window with URL "https://login.xfinity.com/login" so it seems legitimate. The browser window then disappeared and I assumed Thunderbird would now show my emails.

Sadly, Thunderbird did not show updated emails. So I went back to Menu > Settings > Privacy & Security > Saved Passwords and checked the password. For some reason is had changed to another, different, bogus and several hundred characters long.

I have attached a screen shot of the "Saved Logins" window showing the bogus password and another screenshot of the entire bogus passwords before and after I entered the correct password.

I have been pleased with Thunderbird for a long time, but this has me worried.

Can you give advice?

Thunderbird keeps asking for password for 3 email accounts several times

I have 3 email accounts which i unified. when log in I get prompted to enter password for all three accounts which I do, then I get prompted again to enter the password to all Password Manager to save my passwords which I do not want and therefore I uncheck it for all three; I then get prompted again for all three which I enter password, then I get imap login error on my main account which I click cancel a few times before it goes away,

I use Thunderbird portable. How do I fix this issue. it should be that one enters the password for each account once not three to four times. I do not want to use Password Manager to Save my accounts.

Also if ever I have to change password how do I do that? thank for your help.

I have the portable version, download from portable apps website.

I changed my password in my email provider. TB kept saying that it was the wrong password. After a few unsuccessful tries I rebooted tb. It worked. Then, whenever I opened tb it asked for password. I then tried checking 'password manager' and it remembered the password. Fine. Could have been easier. 1. Notice that tb requires reboot to accept password change. 2. Explanation that password manager is "remember password so you don't need to enter every time".

A little more nitpicking: For as long as I have used tb I cannot print a selection of an email. It wants to print the whole thing, along with headers. I have to select, copy, paste to notepad, then print. Could be easier.

When I enter SMTP password, and check the "Use Password Manager to remember this password", it's not remembered

Recently it's a daily occurrence that I must enter the password for my SMTP server. I always check "Use Password Manager to remember this password" but it doesn't help. The next day I'll have to go through this again.

I power on my machine multiple times each day, and I use Thunderbird each time. It doesn't happen each time. It seems to happen only the first time I use Thunderbird each day. This is new behavior. Before it would happen now and then, now it's daily.

I don't have a Primary Password. No need for it.

If you need to see the message I can send it to you, but I'm not attaching it right now because it shows my email address and the smtp destination. Maybe I'm being too careful.

When I tried to delete my old password in "Show Passwords" by highlighting my old password and hitting the backspace key to delete it and every time I click on the background or hit "Enter", it just pops back on where it was so I couldn't correct it without having to click "Remove all" which turned off the "Show Passwords" in "Saved Passwords".

Using Thunderbird to check emails and the calendar for an Infomaniak account: The account was active and working properly. After switching this account to 2FA, Thunderbird consistently requested a username and password during synchronization. After some research, the solution is as follows: you need to create a new app password with Infomaniak, then ensure that Thunderbird saves the password and that the “Require device authentication...” option is disabled. Would it be possible to provide a complete step-by-step guide for next time? Thank you.

I have used Thunderbird for years. Suddenly it asks for my email account password every time I send an email message. What is the problem? The passwords for my email accounts have always been stored in my configuration and it never asked for them. Very annoying.
