That login is for using bitbucket with https url (and I did manage to get it working at the time).
If the https address doesn't work, SourceTree can offer an alternative GUI.
But as shown in this tutorial (or even this one), you could also use GitHub for Windows with ssh addresses.
Make a backup of the ‘github_rsa.pub’ SSH public key file.
Copy the contents of C:\Users\{user}\.ssh\id_rsa.pub to this file and save it.
- Visit the GitHub site and create an account if you don’t already have one: https://github.com/settings/ssh
Account > Edit your profile > SSH keys
- Add a new key with the label: “
Default Public Key (nopass)”
- Copy the public key (
C:\Users\{user}.ssh\id_rsa.pub) to GitHub
The one tutorial I have found for using BitBucket repos with https url is this one (from Jeremy):
- Install GitHub for Windows (GH4W), open program
- Set your username/email globally to get the right avatar in non-github projects
git config —global user.name “FIRST_NAME LAST_NAME”
git config —global user.email “MY_NAME@example.com”
- Add new repository (either preexisting or blank directory)
- In the repository, click the "tools" > "settings" link at the top
- Go to BitBucket, find your clone link -- choose "HTTPS" option
- Back in GH4W, in the "primary remote (origin)" box enter the link you got in step #4
- Update the settings
- Back in the repo view of GH4W, click the "publish" link at the top
- Wait while it spins, then confirm it's there in the remote.
