Two-step Login
With two-step login, anyone trying to access your account must provide two forms of ID:
- Something you know, such as your password.
- Something you have, such as a physical security key or a mobile app.
Some services and websites refer to this as two-step authentication, two-step verification, multifactor authentication, or login verification.
