How can I get rid of that horrible bug of Thunderbird prompting me for my login credentials. Already tried the following: re-adding my Email account, reinstalling Thunderbird from scratch. Nothing has worked.

I have multiple email accounts on Thunderbird (on MX Linux)... att.net, gmail.com and aol.com

While traveling without my computer, i had to reset my aol password on my iphone.

Now that I'm back at my desk, and being unable to find how to change the aol password on Thunderbird, I deleted the AOL imap account and have tried much of today to add a new AOL account.

In the past, I could create an 'app password' within AOL (browser) and use that password in Thunderbird... but that is no longer working.

Any guidance/suggestions?

I am running the latest Thunderbird version 140.17.0esr (64-bit) available in my MX Linux.

I managed to add one email account, but now is impossible to connect any other, it doesn't matter if it's a gmail or a personalised email.

It says: Authentication error.

Unable to log in at server. Probably wrong configuration, username or password

both give me the same error.

Any advice?

Mozilla Account works normally directly inside Firefox, but logging into Mozilla Accounts through Thunderbird's Add-ons manager fails during the Firefox handoff.

Steps to reproduce: 1. In Thunderbird Add-ons, click Log in. 2. Thunderbird redirects to Firefox, showing "Continue with Mozilla account". 3. Click Continue -> Firefox displays "You could not be logged in. Please try again."

Troubleshooting already tried:

• Created a brand-new Thunderbird profile (thunderbird -P) — same failure occurs.
• Cleared cookies/site data in Thunderbird and cleared Firefox cache.
• Disconnected existing Thunderbird/Add-ons connections from Mozilla Account dashboard.
• Extensions and add-ons themselves install and download normally.

I'm using a mailbox.org account with TB. I'm receiving messages from it, so I'm logged in, but TB keeps asking me every so often to login again, and it has three popups in a row each time. How do I turn this off?

I have installed Thunderbird on Linux on a chromebook. When I try to add my (gmail) email account in the Thunderbird account setup screen, it hangs up trying to authenticate the Google password for the gmail account. I have scrupulously checked and rechecked the password and the server details, and they are all correct. Why won't Thunderbird accept the password for my gmail account? Or is something else not right?

I set up thunderbird exactly the same as on my old computer -- i cannot retrieve my emails on the new computer even though the test connection was successful - but i get a pop-up saying autentication failed when i try to get my emails on my new computer, Old computer still gets them

Dear Sir,

I have operated my email

redacted@malcolmgmiller.biz

for many years.

I have forgotten my password and been unable to receive or send emails for some time. I do not know how to access the change your password page without knowing my password.

I do have my customer number but that did not grant me access.

Please assist me in reestablishing my account.

Yours faithfully,

Malcolm G. Miller.

I do not need to write much. My passwords in Google, Microsoft, etc are all in Ibo language (NIGERIA) and no one can decipher it. I have been using them for 15 years, now Mozilla wants me to change it. No, It will never happen. That language is another level of protection. Bye for now.

I keep getting "authentication error" when adding a new email account with Infomaniak, even when I use the app generated password. I am not having this problem with Outlook. I cannot disable Account Hub (1 suggested solution) in Thunderbird 157. what to do?

At one time, I was able to access my email with Thunderbird. Then Thunderbird stopped working, and I didn't have time to research why. Monday, I bought a new Macbook. After installation, Thunderbird says "account settings found." Then it asks for a password. My password no longer works. Instead, I get a message: "Authentication failed. Unable to log in at server. Probably wrong configuration, username or password." What, if anything, can I do?

Since updating to TB 153esr from the previous esr, I occasionally get a server authentication error with imap.gmail.com. Most often they happen when first starting up, but occasionally seem to happen at other times. They seem to be transient as gmail works fine otherwise.

Just wondering if this is a known bug?

I have been having all my email transferred from Yahoo mail for more than a decade, it used to be Frontier net, and i didnt want to change my email, and i havent, so i transfered it on 3 devices because i am very used to the thunderbird format. It still works on my android phone and my HP laptop, but thunderbird will not allow me to sign in to yahoo mail on my PC which is what we use the most for our email, for some reason yahoo made some changes and required a new sign in so i did that on the other 2 devices, however, when the sign in box from yahoo pops up on our PC it always says " OOPS something went wrong" and i called yahoo and they verified it was not them. Which leaves Thunderbird to fix the problem. Please address this as i still Do Not want to change my email address or the Thunderbird Mail which we are used to. Some things are okay just as they are, so i would like some help from your end. Thank you, Richard Sessums.

My setup is Windows 11 Home 24H2 on HP ENVY core i7 Thunderbird 64 bit ver 157.0 updated from 156.?? while chasing this issue. Some time after 08:00 EDT 9/28/26 Spectrum/Charter altered sign-in process, their tech support has been able to fix most customers by changing password on individual accounts. This does not seem to work for Thunderbird accounts. Any attempt to download from my roadrunner inbox attempts for over 60 seconds then fails. Attempts to send from my Thunderbird fails with SMTP server error 10060. Attempts to download from my roadrunner inbox fails with same error 10060 from POP server 47.43.26.4 on port 110 and port 995. I can still send/receive in my roadrunner Spectrum inbox. [redacted] @roadrunner.com, phone [redacted email and phone# from community support forum]
