How to use app password with Git Gui under windows?

[jim-frenzel]

I am using Git Gui (or git-gui) from git-scm.org under Windows and I can't figure out where to update the authentication credentials  to use the Bitbucket app password that I created. If I use the command line interface I get this:

$ git fetch
fatal: Invalid credentials
remote: Bitbucket Cloud recently stopped supporting account passwords for Git authentication.
remote: See our community post for more details: https://atlassian.community/t5/x/x/ba-p/1948231
remote: App passwords are recommended for most use cases and can be created in your Personal settings:
remote: https://bitbucket.org/account/settings/app-passwords/
fatal: Authentication failed for 'https://bitbucket.org/ [...]

Hi, @jim-frenzel, thank you for reaching out to Atlassian Community.

Checking the output you have shared with us, it looks like git didn’t ask you to inform a password, is that correct? If that’s the case, git is probably using some password stored in your Windows credentials. 

Could you please make sure you have deleted all the credentials related to Bitbucket under Windows Credential manager? You can follow the next steps to delete those cached credentials:

• On the start menu, search for Credential Manager

• In the window that will be open, select the Windows Credentials option

• Delete all the entries related to Bitbucket (this will clear all the cached credentials)

Please let me know how it goes and feel free to share any additional questions or concerns regarding this case.

Kind regards,
Caroline
