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.

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 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?

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)

Ive got it set as I recall for imap, but when I open thunderbird I get the google popup to sign in (it does as Ive got the PW right) but it never remembers those ones and constantly keeps asking me wither if I leave thunderbird open or if I close it and reopen it... again the PW's are correct as it DOES log in just for some reason thunderbird isnt saving or remembering them anyone have any idea as to why ? thanks in advance !!

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

Hi Just started using Thunderbird. Every time I start Thunderbird it ask for passwords. As they are long and secure its tedious. I tried the solution previously shown on your web help (click "Outgoing Server" Click Edit. Under "Security and Authentication" DESELECT "Use name and password") but it doesnt give a "username and password opyion" only a box for Connection security, another for Authentication method, another for User name. Whats the best solution please?

I have recently installed 140.7.1esr (64-bit) on Windows 11

1. It keeps asking for my account password, I always check the box for saving to the password manager, with no effect, I still have to type it in every single time. (I did set up pwd manager and I do have a master pwd)

2. Initially I had Thunderbird pick up my Gmail account as well, but it stopped picking up my Gmail for some reason. So I completely deleted my Gmail account in Thunderbird. yet it persistently asks for access to Gmail every 15 minutes. (I get a notification from Gmail saying that Tbird is asking for access to Gmail). The Gmail account no longer exists in Tbird, does not show up in the menu, and it does not download anything from Gmail if I give it permissions.

Hello,

I did change my password. On the IPhone and the webmail page the password is working perfectly, but in thunderbird I cannot connect to the server. It seems, the old password is somewhere registered and still used under Thunderbird. What can I do to use Thunderbird with the new password?
