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 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?

good day, i'm trying to add a new GMX email account to thunderbird, but i keep getting an error telling me that the user name and or password are incorrect, but they are not. i already have two (2 ) other GMX email accounts on thunderbird and they are working just fine. i had a similar issue last week with my Hotmail/Outlook account telling me it couldn't connect for the same reason, but that seemed to work itself out and that one is working fine. i've been using thunderbird for quite a while now and never had any issues integrating GMX email accounts. thank you for your time...Mike S

I'm running Thunderbird most recent version. After changing my Google password, I can no longer connect through Thunderbird to Gmail. I've tried uninstalling Thunderbird and reinstalling. I've tried deleting the Gmail acct info from Thunderbird and setting it up again. I get the pick IMAP screen, enter my new Google password, then get a Google 400 error stating "The server cannot process the request because it is malformed. It should not be retried."

Any ieas?

I double checked all data (IMAP and SMTP ports, passwords, mail adress, ... And I tried it on 2 brandnew computers (one PC; one laptop), running on Windows 11 I've no idea, what else I could do

I can't access to my personal Google account from Thunderbird.

Thunderbird configuration is OK. Cookies authorised.

e-mail account connection process goes this way: - I enter name and e-mail address - I confirm standard configuration found in Thunderbird's FAI database. - Google asks me to confirm that I authorise Thunderbird to share mail, contacts and agenda informations (I was asked my Google pwd only the first time I tried the process). - I confirm my consent - Back to Thunderbirds account configuration window, with "authentication error".

Similar failure when I try to only connect to the contact list or to my calendars (which is my initial will), also from a scholar Google account.

No change after update from 149 .0.2 to 150.0

Since the launch of Thunderbird (Android), I have been using it. Recently I changed the email account password and now want to update it in Thunderbird. I can’t find an option in the app to update the password, and the app is not prompting me to enter the new password.

To open Thunderbird I must enter a primary password. This is driving me NUTS. When I open the program, I want it to start without having to remember a password. Also, if something happened to me, nobody else in my family could open the program without knowing the password and how to find it if needed. After many decades of using this program for email, this primary password nonsense has become a great annoyance. FIX THIS STUPID PASSWORD PROBLEM. Please.

13 Nov. I have been dealing with the problem of the requirement to sign in to Thunderbird using Google. It does not work. I enter my e-mail address, click next, and get a second window that says "Error 400". I tried to get some help with this through a company listed on the internet as Just Answer. That turned out to be a scam.

Someone called me this morning, offering to help me with this problem. The person was from the company The Web Services. While the technician from Web Services was working on my computer for a while to restore my Thunderbird files, he told he that they kept losing the internet connection to my computer. He said they had determined that they kept losing the internet connection, because some hackers were hacking into my computer, while they were working. He showed me a lot of evidence of hacking on my computer, indicating that the 2 technicians from Just Answer who had helped me the day before through long chats were hacking into my computer the entire time they were chatting with me, going through steps they said would solve the problem with having to sign in to Thunderbird using Google. I think the people from Just Answer had tried to create a Thunderbird back-up profile, but had not done it correctly. As a result, all the data within Thunderbird was lost. I cancelled my subscription with Just Answer today.

The technician from The Web Services was able to restore my Thunderbird, including the many local files I have. Some additional formatting of the site still needs to be done, and the correct server settings need to be set up. That is to be finished tomorrow morning. The Web Services person also sold me an anti-hacking firewall, which is supposed to also provide network security.

I am concerned, because on the Mozilla support page, it specifically states that Thunderbird does not offer phone support. I gave this company access to my computer today, so they could restore my Thunderbird files. The Thunderbird files have been restored. Now I see that the issue with trying unsuccessfully to sign in to Thunderbird using Google is still there. So I am right back where I started over a week ago, trying to find someone who can solve the issues that come up when I try to sign into Thunderbird with Google.

I am somewhat suspicious of the company The Web Services, because they called me and offered to fix the problems I am having with signing in to Thunderbird. Please let me know whether it was unwise to let them work on my computer today. Could this be another scam? Thank you.

I can log in and fill in the password, but upon trying to log in, at the end it says "Authentication error. Unable to log in at server. Probably wrong configuration, username or password" I believe this is because the org I'm in requires 2FA for all logins and I can't actually 2FA the login. Thunderbird automatically closes the window that I would use to log into the account and authenticate the connection a few seconds after it appears

I have the latest Thunderbird update. Since yesterday, using imap.comcast.net, I have been getting the error "Login to server imap.comcast.net with username [removed] failed." It wants me to retry or enter a new password. I cannot get emails. I can, however, log into my Comcast email account online and see emails delivered. Thunderbird, of course, will not receive these emails.

For imap.comcast.net, port is 993, connection security is SSL/TLS, and authentication method is normal password. I have not changed any of these settings. I have not changed my password. I have done nothing to cause the problem.

I cannot find a solution online. Could someone help? Thank you!

Attempting to set up a yahoo email in thunderbird 140.9.0esr(64-bit). The goal is to have this set up on multiple workstations, so I've made the adjustments recommended per this article: https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo#w_please-check-the-following-before-asking-for-support

So, the toggle for mailnews.oauth.usePrivateBrowser is set to true, site/third-party cookies are always allowed (no exceptions), and the authentication method is set to OAuth2. Using the recommended server settings for yahoo: imap.mail.yahoo.com : 993 smtp.mail.yahoo.com : 465

I am able to set up the initial OAuth. The window pops up, I log in using the account password then put in the texted code, then the window closes and I get an email confirming the login. Hitting done within Thunderbird after this has it check the password again, and it fails: "Unable to log in at server. Probably wrong configuration, username or password."

This is on a fresh Windows 11 install/fresh Thunderbird install.

As above.

There are two options given "Deny" - when this is enacted the pop-up just reappears again "Allow" - the instructions indicate that if this is enacted data , including contacts, could be deleted. So what do we do?

Hi, i cant log in from my thunderbird from my outlook account. I can do it with two of my acounts but not with the third one with the adress daniel.r.76@outlook.com

Problem with Thunderbird that I use for mail and news.

I have set TB to start with a Masterpassword and store all other passwords. Since sunday I can't use TB anymore.

When I start it, it asks for the Masterpassword which I enter, then it starts and immediately blocks access to all settings because it asks for the newsreader-server password. I can not normally cancel that passwort request nor stop TB, I have to use Taskmanager to quit TB.

Starting TB with the SHIFT option allows me to start it in base mode - but it STILL asks for the newsreaderpassword and won't allow me to change anything.

How can I get access to TB again?

I just updated from TB 142.0 to 148.0.1. After the update, my Yahoo and AOL accounts display a login window and prompted to re-enter the login credentials. After I enter the email address and click 'Next' an error is displayed:

Edge: Too Many Requests

This appears to be a browser error. What is needed to fix this? I am unable to re-enable my email addresses.

When I tried to copy the link to a 'real' browser window I was able to get the verification code from the sites, but then got the error Can't reach this page at 127.0.0.1, connection refused which, of course, is the loopback address.

TB on Windows

Prior to TB 148, OAUTH worked for POP3 access to: Gmail, MS Outlook, and Yahoo.

After TB 148 upgrade: OAUTH to Yahoo fails, subsequent log-in page also fails. Both OAUTH to Gmail and OAUTH to MS Outlook still work fine.

Rolled-back/Reverted to TB 147.0.2 -- OAUTH to all works fine, as it did previously.

Note: YahooMail seems to have other problems. But I was able to confirm successful OAUTH and POP3 to YahooMail after reversion to 147.0.2.
