Support two-factor authentication (BB-7016)
It would be awesome if you could give users the option to protect their Bitbucket account by using a two-factor authentication system.
It would be epic if you used the Time-based One-time Password (TOTP) algorithm specified in RFC 6238(https://tools.ietf.org/html/rfc6238) so it would work with Google Authenticator app for just about every mobile platform.
Thanks for providing a great service! Happy Holidays.
