bonjour à vous utilisateur de thunderbird depuis des années, il fonctionne très bien (j'ai la dernière version : Version 153.0.2esr | Publiée le 4 août 2026

- par contre, il me demande les mots de passe à chaque connexion depuis deux jours - j'ai supprimer le fichier key4 mais lorsque je relance rien ne change ; il demande les mots de passe de tous les comptes.

Auriez vous une solution ? merci beaucoup

Please excuse the length of this but it's necessary.

Began using Thunderbird (TB) in June, 2026 accessing email from wowway using POP3 (I know not imap, but old habits die hard). Changed password on wow in July and changed it in TB. Thereafter, and up until yesterday, TB was unable to logon to wow. However, the new PW allowed access to emails by browser logon to wow; old PW failed as it should. Frustrated with not being able to use TB with new PW: - deleted AppData/Roaming/Thunderbird folder (profiles and all) - recovered a backed up copy of TB folder from mid June when things were working and copied it to AppData/Roaming. Bingo, was able to get and send emails. Puzzled, looked at TB Saved Passwords and verified the old PW was being used. To verify this, I sent an email to myself, pressed F5 to get mail and it was in the inbox, and also on wow server.. BOTTOM LINE: There is no question that TB is using an old, changed wow PW. And if PW in TB is changed to new PW, access to wow fails. How can this be? Help please.

I have 10 email accounts I have to monitor. When I set up Thunderbird on Windows, I entered all the account info and the passwords. I checked the box 'use password manager'. This worked well for a few days. After several days, I started the app again and it asked for every password again. I entered all the passwords again. This happened several more times. I sought help for the bug, but found none. Someone suggested deleting password database files in the Thunderbird data folders. This did not help. Someone else suggested that CCleaner may be deleting password data files, so I added the entire Thunderbird data folder to the scanner exclusion list. Yes, this may be a security risk, but I need this app to work, as I have not found any other app that even begins to get the job done. Ready to start looking for another email app now, unless someone can fix this problem. It is not reasonable to expect me to lookup and restore 10 passwords every time I check my mail.

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?

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.

Since changing my gmail accounts settings in thunderbird under Synchronization and storage so as not to store a local copy of emails. Thunderbird, after a while, is no longer able to authenticate to imap.gmail.com. If i delete the associated oauth2 saved passwords, restart and regrant access. Thunderbird is ok for a couple of hours but then fails again later. Thunderbird ran fine for a couple of days before i changed the synchronization settings.

Any ideas on how to eliminate this annoyance?

I am unable to access my mails on Greenby with Thunderbird and I suspect the password is incorrect. I can read my mails on the Greenby server and know the necessary password but cannot work out how to enter this into Thunderbird! As I am no expert, a simple guide would be most appreciated! Thanks in advance. Roy

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 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".

I'm having so much trouble with Apple Mail and Thunderbird saving my password and I do have an Apple User Defined Password. So, I'm constantly having to input my password. Any suggestion would be deeply appreciated!

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 went to Privacy and Security of the Thunderbird. I went to saved passwords. I clicked on Show passwords. I had to edit the password before I delete that old password.

Thunderbird has not been downloading messages for primary email, [edited]@netscape.net, since March 4. I can't locate where in TB the password is stored for the account.

A NEW password is required EVERY time to make e-mail go in or out: "Set the password for (e-mail address) in mailin.telia.com" and "Set the password for (e-mail address) in mailout.telia.com". Each time I have to get a password from "Telia Webmail" (!). This is happening since Summer 2025. I´ve checked the e-mail account installation details and it is identical to the original (when I installed it first time). I´ve also made a new account (with another e-mail address) but it didn´t help. HELP!

Ive got appx 10-15 accounts in thunderbird about 5 or 6 DONT rememeber or keep the passwords (for gmail)... others do (for gmail)

Windows 11 machine. I have 2 email addresses in my TB set-up, from different domains/servers, one is a Rackspace for my business and the other is Fastmail. I am repeatedly asked for the server password for every single incoming email, and occasionally asked for the SMTP outgoing password when sending. I have put Windows into safe mode and it still happens there. I just don't know what to try next. Thanks in advance, Laurel
