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.

Firefox continually shows pop ups for a passkey and it will not let me sign into a webpage without it. I have seen a way to disable the pop ups online, but I am 84 and not techy. If I cannot stop them, I will stop using Firefox and Use

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.

Hi,

I am unable to get Thunderbird to work after my microsoft password was updated. I get the popup & enter my email & new password, but I never get the second popup to accept permissions. It just doesn’t go any further. I can see Failed login attempts for TB on the microsoft side. I am not too tech savvy, so I’m doing my best to troubleshoot!

This is Thunderbird 78.14.0 on mac 10.11, YES, that is old, it is a legacy mac! It was successfully setup with OAuth2 over 3 years ago & worked fine until the password update. I was able to add TB to an old 10.15 mac & it got the permissions popup & the account was added fine (but it is also using TB 150.0.2). Oddly, there was no 2FA prompts given, it just connected with my password only??

I had a number of devices that needed passwords updated, so I’m wondering if there was a conflict when trying to do this one? Do I need to delete certain files? I found where to delete the stored passwords & did that, but it’s not moving past that point to even store new ones & connect. I can’t grant permissions?

Also, I notice the successful TB login activity shows my IP address, whereas the unsuccessful one shows Browser Mozilla Firefox. I’m not sure if that helps with troubleshooting or not!

Thank you for your time!

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 have been using Thunderbird for 10+years and was able to set up Gmail accounts without any problem. Currently, there are 3 Gmail accounts configured under Thunderbird and those all are working fine. I needed to add one more GMAIL account, everything seems to go through OK, but near the end, it fails with an error message: "Unable to login at the server. Probably wrong configuration, username or password."

I also installed Thunderbird on MAC and repeated the same steps to configure GAMIL account and got the same error message.

The same errors occur if I configure APP PASSWORD in Gmail and then try to configure GAMIL account in Thunderbird using APP PASSWORD. Still got the same error message.

HELP PLEASE

Hi I cannot add my BT mail account. I keep getting authentification error. I can use Firefox to login to my email account so I know the password is ok. The account recently had 2 step verification added. Could this be the problem? My email account has two sub email id's. I have added both these email addresses to Thunderbird and they work fine. I use POP3. The two addresses that were added were done using the automatic installation. I have tried to manually setup the problem address but to no avail.

It may be a BT problem because I tried to change my password, I went through all the on screen prompts and received confirmation of a password change but I still can only login to my emails using Firefox with the old password. The new password doesn't work.

Hi all

I have recently downloaded Mozilla thunderbird, but am having trouble with adding accounts (outlook and gmail). I keep getting the "Authentication failed" error. Have tried other solutions online, like disabling the Account Hub, but nothing changes. I understand that may no longer be a solution. Is there anything else I can try?

Thanks in advance.

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?

Thunderbird stopped working a week ago, and I've wasted HOURS trying to uninstall and reinstall the app in hopes of getting it to work. Best I can do is get it to run, accessing my gmail account, but I'm interrupted repeatedly by screens asking me to choose my gmail account, followed by a screen that asks me to click on a 'give access' button that appears nowhere on the screen. Such a shame that you folks and Google have collaborated in a way that makes a very nice app completely unusable. If you and Google can ever get the access issues resolved, pls advise via email and I make one last attempt to get the app to work: rws.pgh@gmail.com.

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
