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?

I'm trying to resolve password issues. I fear that I might lose access in T-bird as I have through my browser.

T-Bird presently works to receive e-mail at two addresses: [redacted]@pacbell.net and at [redacted]@pacbell.net. It won't let me send email from [redacted]@pacbell.net.

None of my "they did work in the past" passwords allow me to log in with yahoo or AT&T

I want to use the same p- words with t-bird and yahoo and AT&T

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 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.

Probably related to a Microsoft update, Thunderbird started asking for the password of my internet provider almost daily several weeks ago when sending or receiving messages. I am on Windows 11 and that is up to date.

I changed my yahoo password and can longer access this account in Thunderbird.

Now when I sign in to Thunderbird I get 'Edge To Many requests'

Unfortunately I deleted the yahoo user name and password in Thunderbird Password/ Saved Logins thinking Yahoo might automatically ask for my new password when re-starting Thunderbird

Can somebody help please.

Many thanks

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.

After reinstalling a Windstream.net email account I continue to have Authentication Required errors at startup. Popup messages only occurs during thunderbird startup. And Only on my Windstream.net email accounts. not my outlook.com and Gmail accounts.

the following is the popup window during Thunderbird startup.

"Authentication Required - Mozila Thunderbird https://imap.windstream.net is requesting your username and password."

I entered the username and password and check the save box. The popup returns with the same error asking for the same info. If I just select CANCEL, it pops up 2 more times and after the third cancel, the popup shows no more. The account fills with any incoming emails from Windstream.net. The Windstream.net account seams to work normal from that point on. I Can send and receive fine with no more popups. Until I restart thunderbird then this error starts all over. Is this a thunderbird or Windstream.net issue? Any suggestions on a fix? Also I have a gmail and outlook.com account with no issues.

Bonjour, Lorsque je me connecte, j'ai un message que me dit : User is authenticated but not connected et ceci sur toutes mes boites mails. De plus, suite à un changement d'ordinateur mes mots de passe sont visibles aves des chiffres et des lettres credential redacted (see https://github.com/thunderbird/aaq-scraper/issues/15 ) Je ne peux pas voir mes mots de passe enregistrés Je ne peux donc pas me connecter à mes boites mails car les mots de passe ne sont pas valides A savoir que je suis sur certaines boites mail sur @outlook.com (anciennement dbmail)

Pourriez-vous m'aider à débloquer le problème car je suis très embêtée Par avance merci et bonne soirée PS : Si je supprime l'application et que je l'installe de nouveau, vais-je perdre tout l'historique (dossiers, agendas, contacts, etc ...)

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.

I was recently forced to change my gmail password. All of the help messages I found tell me that after I change my email password I have to save the new password to Thunderbird and I don't know where to save it.

When I highlighted the password, it gave me only choices to edit or copy password and the only way I know how to delete a password is to click, "Remove All" and now the "Show Password" button is grayed out.

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".
