I just bought a new desktop computer. It is a Lenovo using Windows 11. I downloaded Thunderbird (.exe) and attempted to install. The installation program does not recognize my credentials. I get an error message that says "Authentication error. Unable to log in at server. Probably wrong configuration, username or password." I have tried every variation I can think of, but no luck. I enlisted Best Buy Geek Squad, and over 2 hours later they have determined that the computer itself has no problems--it is Thunderbird that is refusing to recognize my credentials. I have 4 other devices--2 Iphones, an Ipad, and a laptop using Windows 10, and all have been, and still are, using Thunderbird with no issues. How do I get Thunderbird to recognize my credentials, which are valid on 4 other devices?

Hello, Previously, I had my email with Xfinity, but they stopped this service and set us to Yahoo Mail. I’ve had no luck in setting it up in Outlook, so I tried Thunderbird and encountered the same problem. I have Windows 11. I’m using the IMAP settings recommended by Yahoo. During the setup process, everything checks, but when it asks for an address, which is from Xfinity, and a password, which I’m not sure they’re asking for so I tried the Xfinity, Yahoo, and Mozilla passwords. I get the authentication error on each attempt. Help! Thanks, Parris

If I have a password to sign into my Thunderbird emails, where do I find it. I haven't gotten this requirement in the past so where might I find it now and/or stop those messages?

I had TB on my desktop for years and finally got it also synced to my phone. Then with a failure with Windows 11 had to wipe clean the desktop and start over. Cannot reinstall TB. I obviously have the correct e-mail and password as I was able to log into Mozilla and submit this question. I believe it is a problem with my user name and what is on my phone setup does not work with my desktop reinstallation.

I have Thunderbird on my Win 11 Pro Laptop and on my Samsung Android phone. My primary email account works fine on both devices. My secondary account with the domain name otakorp.org works fine on the Android Thunderbird app, but when I try to set it up on the Windows version it sees that it's a gmail server and sets both incoming and outgoing servers to Oauth2 authentication, but generates an unspecific error (see included image). Any suggestions?

Have a new computer and when they transfered my information they didn't do my email. I finally got found it an downloaded it but now it won't accept my password. Plese help I'm getting desperate. Thank you Mary Ward

Attempting to install Thunderbird on an additional desktop using same address as my original computer has. But when I attempt to install on computer #2, Thunderbird doesn't recognize my email or password from computer #1.

I have tried multiple times to setup a new Outlook email to Thunderbird. I already have one setup and that's fine, but when trying to connect my new email account I keep getting the error

exchange auth error

I've tried everything to fix it.

The setup configuration all goes well, but then connection just won't happen. I've checked in Outlook and I have given Thunderbird permission but still it won't work.

I have the latest Thunderbird on my laptop. I have turned off the hub, but it still appears when I add an account. Sigh!

Please help!

Thunderbird keeps opening a Google authentication window, asking which account to use. I have two gmail accounts (both of which work just fine), and another google account that I manage a calendar for (it works fine as well). How do I work out which account is seeking authentication?

As so many have experienced, but I have yet to find the actual solution, I will bring up the issue.

I recently purchased a new computer. Installed Thunderbird, created all the mail accounts I have and... no problems. All the accounts, once created, populated with emails. For 3-4 days, there were no issues.

Important to note: I let TB use all the default settings. And once everything was up and running >>>>I did not change anything<<<<<.

Then a few days later, I started getting the following messages for two accounts that had migrated from q.com to myctl.net. Entering the 100% proven-correct password results in the know endless-loop of entering the password and the same pop-up error message. The PW is 100% correct as I can go to Centurylinks' website and login using that same, exact password and read my emails.

I've spent enough time trying all the suggestions here, reddit, facebook etc so I'd thought I'd see if anyone has actually found a solution.

hi today thunderbird started showing yahoo popup login and after adding credentials i always get "something went wrong.We could not sign you in. Try again from a different device." Also popup once closed it opens instantly.

Greetings!

I am a lone software developer in my own office.

I do not store my passwords. I type them in every time I log in. It's the only way to remember passwords: type them in every time to reinforce memory.

I want to see my passwords when I type them. I don't want a click option to view them. I want to be able to see what I'm typing every time all the time.

I've been a contributor for a number of years. Please create an option to support my request.

If you need me to program the change, please let me know.  :-) I suspect that it is simply a matter of turning off a property on the entry field. This is my third request.

Cheers, Peter Petropoulos

I have attempted to add a couple of accounts to thunderbird and I have used the correct passwords (they work on other programs) and I get an incorrect password or username flag.

3 дня назад перестали приходить письма - вышла ошибка авторизации. Пароль точно верный (через браузер все работает) и работает Thunderbird на другом ПК. Снес мозиллу, касперского, пробую заново создать почту, не дает, смотрите скриншот 1. Потов выдает ошибку смотрите скриншот 2. Вообще не могу понять что не так! На другом ПК все работает. переносил профиль с другого ПК на свой все тоже самое - ошибка авторизации. Куки разрешены, в исключения gmail.com добавил в Thunderbird Куда копать, что искать?

Thunderbirdの画面でプロバイダアドレスと、gmailのアドレスを2つ使っていたのですが、プロバイダの方が受信ボックスごと消えてしまいました。 coplitに相談して、 送信サーバー、受信サーバーともに設定し直しましたが、「セキュリティとプライバシー」の画面で「パスワード」の行を削除してしまいました。 もう一度、「パスワード」を入力すると、復活するというのですが、その入力画面にたどり着けません。 接続を確認すると、送信・受信ともに「安全な接続が確認されました」と出るのですが、実際の送受信はできない状態です 多分、パスワードが入っていないせいだと思います。AIは受信ボックスをクリックすれば入力画面に遷移するというのですが、そんな画面が出てきません
