I've updated to macOS Sierra and I'm using SourceTree 2.3.1 (69). I've got all my repos setup to use SSH. I'm getting the dialog Password Required For user git on host bitbucket.org. There is a text entry field and the "Store Password in Keychain checkmark.
1) Why am I getting this with SSH?
2) I have tried adding my Atlassian ID password and giving permission to access the Keychain but it just loops as if the password in invalid.
3) all these repos were working before updating to macOS Sierra. However, I did have some issues with the change form the Bitbucket credentials to the Atlassian ID using SourceTree but they seemed to be sorted out.
