Two-factor sign-in
In short and in plain language
Two-factor sign-in means you need more than your password.
You also need a further proof. This can be a code from an app or a text message. Or you confirm the sign-in on your phone.
A stolen password alone is then usually not enough to get in.

With this kind of sign-in you need a further proof in addition to the password. This can be a code from an app or by text message, or a confirmation on your phone. A stolen password alone is then usually not enough to get in.
