Use SecureAuth Authentication
You can utilize Multifactor Authentication with SecureAuth, which generates a 6-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.
Please note that if you have more than one Multifactor Authentication option enabled for your account, you must select your desired default authentication option from the drop-down menu at the bottom of your Multifactor Options window in order to be prompted to authenticate with your preferred option when logging in to LastPass.
