why source tree asked for bit bucket password where I didn't update any account settings

[Hrishi]

Source tree asked for a bit bucket password where I didn't update any account settings.
Every time I do some fetch or pull operation then I saw above Pop Up.
After inserting the correct password I am not able to log in where I am able to login into bitbucket (https://bitbucket.org/).

I am not understanding why this happens

I have this same problem. I found a workaround that if I refresh the OAuth token under Tools -> Options -> Authentication, select the bitbucket account and hit "Edit" and then the "Refresh OAuth Token" it will function for that day, but I've had to do this every single day. This just started happening in the last few weeks.

I changed over to OAuth from basic authentication just a few months ago. The timing of this problem seems to be in line with the ending of support for Atlassian account password usage:

"Beginning March 1, 2022, you will no longer be able to use your Atlassian account password when using Basic authentication with the Bitbucket API or Git over HTTPS. For security reasons, we require all users to use Bitbucket app passwords."

I'm guessing there are some Atlassian credentials stored somewhere but I haven't had the time to figure it out yet.
