Oauth2 authentication failing on Thunderbird

more options

Hello,

I have been using Thunderbird for years to collect all emails in one place with out issue. In the last few days authentication has started failing. It started on one gmail account prompting for a password. When I enter the password it is rejected. A second GMail account is now doing the same and one of my Yahoo accounts is now doing it too.

I can still access the accounts on my phone using Oauth2.

Nothing I have tried fixes it. I am in danger of losing access to all my of my email accounts on windows.

What is going wrong?

Problem solved.

I didn't delete anything or restart in safe mode. I added the same account again as IMAP. The password was accepted and the problem is fixed. Oddly, the pop version is no longer throwing errors. I didn't delete it or change any settings. I have also logged in to the associated google account and updated the recovery data. It already had a valid recovery email address, which it didn't use.

So problem solved.

Thanks for the input Christ1 and Tarik.

What is the exact error message?

Please post your Troubleshooting Information. At the top right of the Thunderbird window, click the menu button ≡, then select Help > More Troubleshooting Information. Press the "Copy text to clipboard button" and paste the information into your reply.

Are you using your main account password or an app password?

What is your anti-virus software?

Antivirus is defender and malwarebyte.

It's account 8 in the data below. The password is generated by Oauth2. The initial permission is the password for the associated google account. That is the password which is now failing. I can still send and receive on the affected email account using K9 on android.

Could this problem cause be that this gmail account is pop and the others are IMAP?

You have to restart your Windows in safe mode. I had the same problems as you have (passwords failed to be recognized) and now it works fine .

No, I don't think so. You can try to delete the OAuth authentication token Thunderbird has remembered for the troubled account. Then restart Thunderbird. You should then be prompted to re-authenticate your account. Make sure cookies are enabled, and use your main account password.
