Cannot pull, commit and push on SourceTree Mac.

[Ainul Yaqin]

I want to pull and it give an error like this:
Bitbucket Cloud recently stopped supporting account password for Git authentication.

after that I input required password but it still error with another message:

git -c color.branch=false -c color.diff=false -c color.status=false -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree fetch origin 

Completed with errors, see above.

What should I do? Thank you.
