I had an email Atlassian today saying I must start to use App Password for linking with BitBucket.
I use:
Up until now I have always input a passphrase each morning I do my first commit and there after I get no prompts.
I have followed the instructions to create an App Password but I do not know how to change TortoiseGit / Pageant to use this new App Password.
You only need to use an AppPassword when you're not using an SSH key for authentication.
IIRC the AppPassword can just be entered as a password when you use an HTTPS-based remote.
