Thunderbird Community Forum

After many years of using Thunderbird I am now considering ditching it. I am continually getting the Authorisation Failure message when trying to open Thunderbird. Why does this keep happening? It does not happen on my Android devices, just on Windows 11. I have tried deleting all three gmail accounts and re entering them. All is fine until I close down Thunderbird and then open it again. I run Norton 360 and have tried taking off Norton email security, but that didn't work. Any ideas, please?

I've had a Thunderbird email account for years. My laptop quit, so I've set up the account on a new laptop. I discovered that I hadn't saved my Thunderbird password, so I followed the procedure for "forgot password". This included a new p/w, and I also got a Mozilla PIN (for future Microsoft Password Manager use), and got a Mozilla Account Recovery Key, again for future use. But I can't log into my Thunderbird account. I get the message "Authentication Error" (Wrong p/w, email, etc.) Changing IMAP / POP settings didn't help, though I did go with the recommended IMAP setting.

Any suggestions?

I've had issues with google and microsoft, changed passwords, now I get credentials messages when Bird tries to get email. I know its because of my password changes but can't fix it. (I edited this because I said authentification before instead of credentials)

loaded Thunderbird on new laptop and set up account getting error message that ID or password incorrect. I'm able to login to my email account using web browser with ID and password. I have check settings for the AT&T mail server and everything looks correct. Need help what am I missing?

For a week or two I haven't been able to send any email from Thunderbird. I use smtp.gmail.com as my outgoing server, and have it configured using SSL/TLS on port 465 with Oauth2 authentication. I first saw this on an older TB version, but have now updated to Thunderbird 152.0.1 on MacOS Sequoia 15.7.7.

When I try to send email, a dialog pops up saying "Enter credentials" for my account, then "Verify it's you". When I click on Next it asks me to "Complete sign-in using your passkey". I believe at this point another window is supposed to pop up and I can use a fingerprint to enter the passkey, but that window never pops up. I have tried 3 different default browsers: Firefox (my usual one), Google Chrome, and Safari. All behave the same. Firefox might be suppressing Javascript, but the other two certainly aren't.

Is there some system security setting that might be preventing Thunderbird from opening a window in the default browser, or does Thunderbird maintain its own record of the browser? Any other suggestions on how to get the passkey challenge to appear?

TBird connected to AOl fine for several years. Now, today, TBird tells me that my AOL password is incorrect. I changed the AOL password but TBird still does not work. I can sign on to AOL just fine using Chrome and going to the AOL web site, but TBird will not sign me in. Please help.

Really weird problem with a friends thunderbird setup.

All of a sudden my friend was unable to get here emails. It kept saying the password was incorrect. Of course she didn't know her password but it was saved in Fire fox. Found the password and verified her centurytel webmail works. So put it in Thunderbird and still give me an error. I then decided to install Thunderbird on my personal laptop and everything works fine. So I decide to do a clean install, deleted all profile folders and everything. Reinstall Thunder bird and get an "Authentication error". I tried disable all her firewalls on her computer (Windows 11) and disabling the firewalls on the router/modem itself. It still doesn't work. I think next thing I will try is my laptop that has thunderbird installed with her email account.

Any other ideas?

Google sent notice that my password had been compromised, so I changed it. When I went back to Thunderbird to open email I got a popup to change my password, when I clicked NEXT I got a Message that said, "The server cannot process the request because it is malformed. It should not be retried. That’s all we know." Then I got an email through the Gmail website providing me an authorization code, but I have no idea where to enter that code. I've been working on this issue for a few days now and am in a Catch-22 situation with no idea how to proceed. Below are screenshots of the responses I've gotten so far. Suggestions???

I'm trying to add a Roadrunner email account to a new instance of Thunderbird (I bought a new computer).

The Roadrunner account already exists in my Thunderbird account and on the previous instance of Thunderbird.

When I attempt to add the Roadrunner account, Thunderbird rejects the Roadrunner account's password. Note that I can use the password get into the account on the Roadrunner site, but Thunderbird won't accept it. Of course,

Thunderbird's error message is vague to the point of being worthless, so I don't know why the Roadrunner account is being rejected.

What am I doing wrong?
