I tried searching for the answer here but didn't really find it. With more and more places going to Passkeys over traditional passwords, how does that work with Thunderbird? It's not like we have the typical login credentials to setup under the account settings.

Thanks

Something changed a few weeks ago (about November 30) and since then Thunderbird will not allow me access to any new emails, nor to be able to send new emails.

Instead, I get a large pop-up window which basically says "Enter credentials: Mozilla Thunderbird Email wants to access your Google Account <my email typed here> This will allow Mozilla Thunderbird Email to: Read, compose, send, and permanently delete all your email from Gmail".

I don't want anyone to permamently delete any of my emails, nor do I want anyone sending emails from my email account (etc, etc).

SO I click deny, and the pop-up goes away - that is until I try to use Thunderbird and it pops up again.

I've been using Thunderbird for many years and never had this problem before. Do the Thunderbird or Mozilla techs know anything about this and how do I fix it, or is it a new policy (which means I will no longer be using Thunderbird)?

I have searched here some time in December but nothing suggested by other users worked for me.

I've read everything apropos here, tried everything, and I'm lost--and totally screwed--if I can't get into my old Thunderbird. Spectrum, computer died, nobody competent here to get past "Registry Error," I guess, but I need all the data, contacts, calendar, etc., in the T'bird I've relied on for MANY years. PLEASE help. I tried to get a screen grab: It didn't work.

This is the second time I've appealed for help.

I have downloaded the latest Thunderbird (for Windows). I have tried setting up my Gmail account in it but just get a failure. Not sure what I am doing wrong.

I start the account setup, set my email address and password and click continue. It shows an automatic IMAP configuration, I click Done. A window pops up from Google for me to allow Thunderbird to access my Google Account. I click Allow. The window goes away and It goes back to the account setup screen with a yellow error box saying "Unable to log in at server. Probably wrong configuration, username or password."

I know my username and password are correct. Any suggestions?

Hello I keep getting the attached message to sign into Thunderbird with my Google account as per the attached image. It is only recently that the message keeps appearing which is very annoying. I have tried various settings but nothing seems to work. What can I do to get rid of this message? Thanks

Hi there Thunderbird Community,

I am first time user of Thunderbird, and I am using version 140.2.0esr (64-bit).

I have been trying to connect my Gmail account, and it keeps on giving me this error that I have seen on other threads: "Unable to log in at server. Probably wrong configuration, username or password."

From the other threads, I tried to do the troubleshooting suggested:

 - cleared the cookies associated with Google
 - added https://account.google.com as an Exception for Cookies and to always allow
 - disabled Account Hub since it seems to have issues from what I read on another thread
 - changed my Google account password
 - tried another Gmail account with no success
 - tried various Thunderbird versions, uninstalling the old one before reinstalling the new one:  Thunderbird Release (Recommended), Thunderbird Extended Support Release (current version being used), and Thunderbird Beta.  I have not tried Thunderbird Daily.

I have added Google OAuth screen-by-screen images of what I saw before getting the Thunderbird client error message.

Any ideas?

Thanks! James

While trying to retrieve new messages for one of my email accounts, I keep getting the message "Login to server xxx.xxx.xxx with username xxx@xxx.xxx failed."

I click the "Enter New Password" button and enter the same password that I use to successfully login to the account on a browser, and it STILL fails and keeps showing the same message box.

This started happening this morning. Have others reported this problem? What do I need to check to see if there is a problem in either Thunderbird or in my email account settings?

Thanks for your 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.

Recently many sites have (for reasons I cannot fathom) introduced a pre-login form: ie a form that requires a username to be entered before an password text box is provided. This seems to be a trend and it is incredibly annoying.

The issue I have is that FF does not recognise the page/form as a login page and therefore does not provide a list of usernames for the domain in question.

Any advice or help would be very much appreciated.

Hi, I had the idea to try Opera browser as I saw various videos about it. Firefox does slow me down at times even though it's what I have used for years.

Soon after, I defaulted back to using Firefox but the settings must have gotten changed. Everytime I wish to log in to any site, I have to type in my email again. The passwords usually are the old ones that show up.

With Amazon for instance. I must sign in and verify with codes sent to my mobile few times a day. I have searched for help online and gone through the cookies and history and privacy settings, turn this on or that off, don't do this and don't do that. Despite all that, the sites don't remember my email logins. If I go from voucher code to another site, it doesn't remember my credentials, so I don't get the deal or voucher. Amazon on my mobile works perfect but on my laptop, it's just a nightmare to have to sign in and verify each time. Outlook refuses to recognize my password most times and so it goes on.

If I cannot fix this asap, I will then have to remove Firefox as a browser altogether and find anything else that works! Please advise. Last time I reached out to Firefox, I never heard back! Fingers Crossed x

I removed Gmail from my Thunderbird after Gmail became unreliable. (I had Gmail coming through T-bird for many years with no hassles..). I then attempted to re-install the Gmail client in T-bird using Gmails directions. Gmail took over my Thunderbird account! I then removed the Gmail account completely... I now get a notice in Thunderbird to sign in with GOOGLE after all my T-bird imap access is done and Tbird is open. The page (Google notice) which appears asks me to sign in with Google account. I want to get rid of this annoying notice. The notice can easily be dismissed but it is really annoying when it appears every time I open T-bird. Any ideas or help much appreciated! ..Btw - I attempted to get help from Google and they dismissed my case saying it was contrary to their policy etc....!! Help!

I have a Hotmail account and multiple gmail accounts. When I try following your (obscure) instructions for changing passwords, the box of passwords is only for my gmail accounts. None for my hotmail.

As Hotmail is very important to me, I'd like to keep accessing it through TB but you make it tough.

I am now not receiving my Hotmail mail and as I get too much traffic 200+ msgs a day, it will build. Please send simple, direct instructions on how to find and change the hotmail password, thank you.

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.

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)

I have a password. It works fine on Wave webmail. It fails on Thunderbird. It is not a typo, I am pasting it from my password storage.

How do I set a password in Thunderbird that works?

Hello group!

Trying to set up a new email account on shaw.ca, I get a hard error message: "Unable to log in at server. Probably wrong configuration, username or password" from Thunderbird.

I can send & receive emails via webmail, so all is Kosher at the server side.

Except Thunderbird kicks up a fuss. There's a little dialog box that says "Checking Password", with a tiny blue arrow that moves back & forth, seemingly forever. And then stops cold with that message.

I am not the first to have this problem: https://support.mozilla.org/en-US/questions/1495062

His attached screenshots are almost identical to mine, but for the Hostnames being shaw.ca, rather than gmail.com.

And my flavor of TB: 128.14.0esr (64-bit) Thunderbird for Linux Mintmint-001 - 1.

Any suggestions, anyone?

Thanks in advance,

- Ralph
