Invalid Username & Password error while pull or push on the source tree

one of my repositories available in one workplace but at the time of pull or push, it gives me an error.

git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks push -v --tags origin master:master
remote: Invalid username or password
fatal: Authentication failed for 'https://bitbucket.org/yashusstechteam/wechecked_prod.git/'
Pushing to https://SanketPathak@bitbucket.org/yashusstechteam/wechecked_prod.git
Completed with errors, see above.

Please help me resolve this
