Additional account protection
Two-factor authentication significantly strengthens web sign-in security.
In addition to the password, web sign-in can require a time-based 6-digit security code from a standards-compliant authenticator app. Recovery codes provide an emergency path, while trusted devices can be stored for a limited time when permitted.
