I'm trying to put thunderbird on my laptop, but after entering the password I keep getting an error message saying the password or settings must be wrong. But I've checked the incoming & outgoing settings, my password a few times now & I know everything is correct. So why do I keep getting this error message & is there a way to fix this? I'm running windows 10.

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

Thunderbird 148+ on Windows 11 repeatedly prompts for the password when synchronizing an Exchange account (professional) configured with the native Exchange support (no add-on installed).

The account only offers “NTLM” or “Normal password” authentication methods. OAuth2 is not available in the account settings.

During synchronization, Thunderbird asks for the password separately for many folders. However, clicking “Retry” usually works immediately without changing the password, and manually re-entering the same password also works.

The issue then reappears for the next folder, causing continuous authentication prompts (I have many folders...).

Actions already tested:

• deleting saved passwords and tokens,
• deleting/renaming key4.db and logins.json,
• restarting Thunderbird,
• recreating the account.

The problem persists.

This looks like an authentication/session handling issue rather than an actual invalid password.

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?

Hello,

After moving my Thunderbird profile to a new computer none of my accounts can authenticate. I followed the instructions here: Move Thunderbird data to a new computer, using "An alternative method for manual transfer between Windows 10 and Windows 11 computers." What explains the response in the attached image, "Something went wrong," and how can I fix it? Happens when I click "Next", the first step to log it.

I have a related problem with other accounts set up in the profile. This one is using Oauth2. I tried switching to password, and hand a similar problem. I tested the connection to the server in Settings for the account and it was successful. Same for the others. They all authenticate successfully on my old computer.

Thanks...

When I try to access my email on Thunderbird, I keep getting the same message: Login to account "jayoung3@icloud.com" failed Login to server imap.mail.me.com with username jayoung3 failed.

I changed my password but I still can't access my email. And I have an account recovery code (which I don't know how to use).

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 filled in an un-correct password a number of times due to incorrect language setting of my keyboard. Then the popup window for this disappeared, and I cannot find a place to enter password. What can I do? It is the password for outgoing email.

In setting up a new PC (laptop), I must make my password known to the software. But I cannot remember my password. On my existing, older, laptop, I saved my email password long ago i.e. I do not have to enter my password, on the older laptop in order to get email. I no longer remember my own password. How do I find my password on my existing, older, laptop ? Thank You. <[edited from public forum] @attglobal.net>

I am trying to reinstall Thunderbird on my computer using Windows 10 and I get a pop-up box requesting to sign in to my Google account and then an authentication error message. How do I get past this?

I had to reinstall windows 11 on my laptop so I also had to reinstall Thunderbird, but the latter will not accept my email & password (same as on my desktop). (I do not use hotmail or outlook, just Thunderbird.) Is there something I'm missing?

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?

I received an email message from earthlink which included a verification code that I did not request. Earthlink support told me to change my password immediately which I did. Now when I open open Mozilla on me laptop, it requires me to put in the new password. How do I change the password/login that Mozilla uses to access earthlink?

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

It has been going on for two days. I tried restarting in troubleshoot mode and it didn't turn on the "Show Password" button. The version of thunderbird I'm using is Mozilla Thunderbird.

When I got into the "Show Passwords" in "Saved Passwords in "Privacy & Security", I had to click "Remove All" in "Show Passwords" to delete it, and now it turns off the "Show Passwords" in the "Saved Passwords" section, and now the OAuth2 is missing.
