Due to this I am unable to perform any activity namely pull ,Fetch , Check-in with bitbucket as it contains source repository.
When I tried to perform above mentioned activity through Visual Studio getting below error message.
Your Bitbucket account has been locked. To unlock it and log in again you must solve a CAPTCHA. This is typically caused by too many attempts to login with an incorrect password. The account lock prevents your SCM client from accessing Bitbucket and its mirrors until it is solved, even if you enter your password correctly.
