Asked by idk
You decide to open a checking account at a nearby bank. You log into their app for the first time, and you’re asked if you would like to set up two-factor authentication (2FA). It’s optional, and you’re considering using it.
How does 2FA keep your account more secure?
Question 6 options:
It requires a second method of verification to log in, such as a code sent to your phone.
It makes it impossible to access your account on any other devices.
It requires a more secure password that would be impossible to guess.
It makes it impossible to log in to your account without biometrics, like a fingerprint.

Correct answer: It requires a second method of verification to log in, such as a code sent to your phone.
Why: Two-factor authentication adds an extra layer beyond your password (something you know) by requiring a second factor (something you have, like a phone that receives a code, or something you are, like a fingerprint). This helps prevent access even if your password is stolen. The other choices are inaccurate—2FA doesn't make access impossible on other devices, doesn't itself enforce a stronger password, and doesn't always require biometrics.
