How does two-factor authentication work?

Modified on Mon, 31 Jul 2023 at 09:58 PM

First of all, you need to download the authentication app in the iTunes app store or Google Play app store. If you have enabled Two-factor authentication, to access your account you need your normal password and a one-time verification code generated in the app on your mobile device.

  1. Whenever you sign in to you will enter your username and password as usual.

  2. Immediately after you will be asked for a one-time verification code that will be generated in the authentication app. The code changes every 30 seconds.

  3. If both codes are correct you will now have access to your account.

To install the free authentication app on your mobile device, go to the app store on your mobile device and search for LastPass Authenticator.

Alternatively, follow these direct links for iOS and for Android, and for Windows Phone.
