Add more security

Protect your LastPass account by requiring two-factor authentication codes when you sign in. Two-factor authentication enhances your digital security by protecting your account with an extra sign-in step. Even if your password is compromised, your account cannot be accessed without a two-factor authentication code.

You can even mark a device as “trusted” so you don’t have to enter codes on that device as long as your account is secured with two-factor authentication.


To enable LastPass Authenticator for your LastPass account:

  • Download LastPass Authenticator to your mobile device.
  • Sign in to LastPass on your computer and launch “Account Settings” from your vault.
  • In Multifactor Options, edit the LastPass Authenticator and view the barcode.
  • Scan the barcode with the LastPass Authenticator app.
  • Set your preferences and save your changes.

LastPass Authenticator can also be enabled for any service or app that supports Google Authenticator or TOTP-based two-factor authentication.


To sign in to your LastPass account or other supported vendor service:

  • Open the app to generate a 6 digit 30 second code OR approve/deny automatic push notification.
  • Alternatively, send an SMS code
  • Enter the code in the login prompt on your device OR click “approve/deny request”.
