On Twitter Status:
We’re committed to keeping Twitter a safe and open community. As part of that commitment, in instances when we believe an account may have been compromised, we reset the password and send an email letting the account owner know this has happened along with information about creating a new password. This is a routine part of our processes to protect our users.
Hello Twitter! When are you starting to support 2-step authentication? Just like every serious service is offering today.
