Why Two-Step Login

Learn why two-step login is in place at UC San Diego.

Enabling two-step login is the single most important measure UC San Diego can take to protect networks and applications from hackers and other malicious actors.

Login credentials are more valuable than ever and are increasingly easy to compromise. Credentials can be stolen, hacked, or guessed, and you may not even know when someone else is using your account.

Two-step login increases account security by preventing anyone but you from accessing your account — even if they know the password.
