When signing up for the Service, users are required to either provide their email address and a password while creating an account with us, or authenticate with their version control system identity (GitHub or Bitbucket). When users log in to the Service using sign-in services such as OAuth (for example, login with a GitHub account), these services will authenticate a user’s identity and provide the user with the option to share certain Personal Data, such as name and email address(es), with us.
