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.

I've been using Thunderbird for years to access my gmail account through my ieee alias. Sometime after 4/2/2025 my login fails with the message "Login to server imap.googlemail.com....failed". I've tried changing the imap server to "imap.gmail.com" but get similar results. For some reason, it appears that something changed on 4/3 that prevents a successful login to the gmail server from Tbird. I have both Tbird and gmail configured for OAuth2. Update: As it turns out, following the steps in this link resolves the issue: https://support.mozilla.org/en-US/questions/1375558

I reinstalled thunderbird and cleared the profile folder. Then when I login Gmail, after the OAuth, it tells me "Unable to login at server. Possibly wrong configuration, username or password."

This only happens to Gmail. I also tried Outlook and this didn't happen.

I then tried running thunderbird in the terminal to see what it outputs: (image 2)

"line 232: Script terminated by timeout"

Technical information: TB version: 128.5.1-1 (arch linux aur)

I am writing to request assistance with my Mozilla account. I am unable to access my account due to several reasons: I have lost access to the two-factor authentication app, I have lost the backup data with the 10-digit recovery key, and I no longer have any devices where I was previously logged in. I only have access to my email address.

I do not need access to the synchronized data; it would be acceptable if you delete it and allow me to register a new Mozilla account with my existing email address. Using a different email address is not an option for me.

I am in the process of transitioning away from the Google ecosystem and would like to use Mozilla's services and products. Could you please help me reset my Mozilla account so that I can register a new one with my current email address?

Thank you for your prompt attention to this matter.

Best regards, Evgeny

For years I used Thunderbird to process my Earthlink emails. Thunderbird suddenly stopped accepting my Earthlink password, which I repeatedly tried and reset. Is something wrong with my Thunderbird settings? Mac IOS 13.7.1

I have several email account set up with Comcast and am able to sign on to all but one with Thunderbird. That one gives me the login has failed message to enter new password or try again. I've compared the settings on that account with the others that work and they appear to be correct. However when I check saved passwords, that account is missing the smtp line for the POP account. At this point, I've run out of ideas of what to do, short of deleting that account on Thunderbird and setting it up as a new account. Help! Thanks.

suddenly I am asked for passwords on my two email accounts, and when I enter the passwords, which are correct as I've checked with my ISP...I am not able to access my email at all. Email programme was working fine about three hours ago, and now...well I am continually asked for passwords for my accounts, and then told they are incorrect? I've shut down Thunderbird after reentering passwords, have double checked settings, and had to change IMAP setting to mail. etc., as that is what my ISP has told me to put and have also changed it back to imap, but still cannot access my emails at all.

Please someone help me sort this out, it is doing my head in...and this isn't the first time Thunderbird had done this with password issues either///GRRRR

I've had trouble with this in the past where logging into Ring won't let me get past my user name/email address. I can hit enter, reload the page, try using tab but nothing works. Then for some unknown reason it will go forward to the password. But this time it just won't let me proceed no matter what I do, the continue option stays grayed out. I can sign on using Edge but I don't want to use Edge or even have a second browser open just so I can see my security camera. I want Firefox to work correctly.

For whatever reason my request to stay logged in on certain sites is not work. Each time I close a browser or turn of my computer I have to log back in again. I have cleared the history and the cache and rebooted and it still does it.

Fired up 128.2.1 this morning -- worked fine. Pulled email of my Office365 and gmail accounts no problem. Noticed there was a point update to 128.2.2 - applied the update, but now both Office365 and Gmail fail to authenticate. Time out.

Anyone else seeing this?

This just happened with a new update on only one of my two gmail accounts 128.2.3esr

I was not getting email on one account, so I deleted that one account. Now I can't add it back to TB. I get "Unable to log in at server. Probably wrong configuration, username or password." Double check password and logged on with it on Edge browser, no problem.

I uninstalled / reinstalled Thunderbird with the same result.

Thank you!

I thought I posted yesterday but I can find the post. I am having trouble with Firefox keeping me signed in to websites that I use, including my own! I have cleared the cache and history, rebooted, signed in, shut the browser and then when I come back I am logged out again :( Costing me a lot of time and inconvenience :(

Today I changed the password on one of my gmail accounts. I edited the password in Settings in 3 places: imap, smpt and oauth. Next time I started Thunderbird I got a gmail authentication pop-up. Se first screenshot. The email address was shown correctly. When I clicked Next, I got the failure message. See second screenshot. I rebooted and tried many times with same result.

I have several other gmail accounts on this same Thunderbird client and they continue to work correctly. I know my password is correct because I can access this email account both directly on gmail and also on another computer where I set up Thunderbird just to test for this problem.

Any idea what is going on and how to fix it?

I can’t complete the steps to change to OAuth for my Hotmail account.

The Microsoft site says to change the Authentication Method on the SMTP Server dialog to OAuth. But the authentication method drop down list doesn't include OAuth. Here are the only options in the list:

• No authentication
• Normal password (this is the one I currently use)
• Encrypted password
• Kerberos / GSSAPI
• NTLM

I use Windows 11 and Thunderbird version 128.20esr (64-bit), Windows.

How do I fix this problem?

Thunderbird just updated to this new Nebula version and now my Gmail account isn't working. I have other accounts setup and they seem to still work (Outlook based) It sits there trying to sync my calendar or I get Checking mail server capabilities. It also doesn't shutdown when I exit Thunderbird. What is going on?

In trying to sync my bookmarks from my old PC to my new one (Win 11), every. single. time I log in to Firefox, and enter the emailed code I receive, to which I get an on-screen conformation that I've logged in AND an emailed confirmation that I've logged in, I am instantly logged back out- the little yellow triangle shows back up on my account icon. I have tried everything i can think of: I've made sure I'm not in private browsing mode, cookies are enabled, I've forced a log out of all devices, I've closed and re-opened Firefox, I've restated my computer, I've even uninstalled and re-installed Firefox in case there was some odd glitch....all for naught. Nothing I do helps. THEN to make matters worse I get the 15 min blockout to add to my frustration, because I've tried this too many times. All I want to do I sync my bookmakers to my new device....

Hi.

I've been at it for an hour now. Found nothing in the help, a few things in Google that no longer work... I've updated my MS password including Hotmail/Outlook.com, so no I need to do that in Thunderbird. I can't find where that's done ? (thunderbird windows latest release)

"account parameters" has something for the SMTP server, but not for the IMAP one.

Thanks for any help.

I read that I now need a secure mail key so I can access my emails with third party app Thunderbird. I have created a secure mail key at att.com which is part of Yahoo. My email app is att.yahoo.com. I was told the passwords for Thunderbird would be within the profile under the Profile Folder but I cannot find them there. All I want to do is update my password within the Profile Folder and it seems like it would easier to break into Fort Knox.
