Can't login to my BitBucket account from SourceTree

[bholm]

I have a new computer and needing to setup my SourceTree access to my BitBucket repo. But when I try to connect via HTTPS (I don't have SSH setup) it says I should login using my username instead of an email address. But when I login to BitBucket.org in a web browser, I login using my email address. There is no indication that there even exists a username for the account. 

Why am I experiencing this strange error? It won't let me connect!

Hello Jason,

Thank you for reaching out to Community!

When using the Jira app or accessing Jira on a browser from a mobile, it will work the same as on a computer. When the user adds the email address to log in, it will recognize that the account is associated with an Identity Provider, and redirect the user to login using SSO.

If you have any other questions regarding this matter, please let us know.

Regards,
