Use the Google Authenticator

Google Authenticator is a multifactor app for mobile devices that generates timed codes used during the Two-Step Verification process.

Note: Feature availability may vary depending on your account type.

For LastPass admins, it is recommended that you complete the steps for enabling Multifactor Authentication in the Admin Console.

Set up the Google Authenticator app

  1. Install the Google Authenticator app on your iOS or Android device (more details for each device type can be found here).
  2. In the Google Authenticator window, click View your barcode in the "To get started" section at the top of the window.
  3. When prompted, enter your Master Password then click Continue.
  4. On your mobile device, open the Google Authenticator app, tap the Add icon or Add an Account option, then tap Scan barcode.
  5. Use your device camera to scan the barcode, which will automatically populate a new entry for LastPass in the Google Authenticator app.
  6. Back on your web browser in the Google Authenticator window, click OK once the barcode has been scanned.
