I just created bitbucket account. I was trying to clone my codes from Xcode with those steps:
1. Clone respository
2. Select Git type
3. Paste my https string
4. Select use user name and password
5. The username is filled with my bitbucket user name automatically
6. I typed in my password.
7. Click on Clone button
Soon I got failure with error type Authentication failure.
Not sure which step I did wrong.
