HTTPS Credentials in SourceTree (Windows)

I’ve recently enabled 2FA for my GitHub account and came across an issue pushing to another GitHub account on SourceTree. Yes, I am using HTTPS instead of SSH.

Apparently, SourceTree for Windows stores the credentials in Windows Credentials (Control Panel\\User Accounts\\Credential Manager\\) so I deleted them and tried to git fetch which SourceTree for Windows prompted me for my username and password.
