Use SecureAuth Authentication

You can utilize Multifactor Authentication with SecureAuth, which generates a 4-digit, OTP (one-time password) code via SMS/Text message or via the SecureAuth app on the user's mobile device that they can use for authenticating as they log in to their LastPass account. The SecureAuth Authenticate mobile app is available for iOS and Android.

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

To get started, LastPass admins must complete the steps for enabling Multifactor Authentication in the Admin Console.

Once the administration steps are complete, LastPass users can set up and use SecureAuth.

Set up the SecureAuth Authenticate app

  1. Download the SecureAuth Authenticate app on your iOS or Android device.
  2. Follow the instructions to Connect an Account to your User Profile.

Set up and configure your LastPass account

  1. Log in to LastPass and access your Vault by doing either of the following:
    • In your web browser toolbar, click the LastPass icon LastPass then click Open My Vault.
    • Go to https://lastpass.com/?ac=1 and log in with your email address and Master Password.
  2. Select Account Settings in the left navigation.
  3. Click on the Multifactor Options tab.
  4. Click the Edit icon Edit option for SecureAuth.
  5. For the "Enabled" option, select Yes from the drop-down menu.
  6. For the "Permit Offline Access" option, use the drop-down menu to choose from the following:
    • Select Allow if you wish to allow access to LastPass even when you are offline. This will store an encrypted Vault locally so you can log in without using Multifactor Authentication in case of a connectivity issue.
    • Select Disallow to prevent offline access, which requires the use of Multifactor Authentication and to be connected to the internet when using LastPass.
      Note: If this option is selected and you are not connected to the internet and/or https://lastpass.com is not available, you will be unable to access your Vault. Learn more about offline access.
  7. When finished, click Update.
  8. Enter your Master Password, then click Continue.
  9. Enter the SecureAuth User ID to confirm.
  10. If prompted, enter the 4-digit code that is generated on the SecureAuth Authenticate app.

SecureAuth is now enabled for your LastPass account.
