How do I set up LastPass to use passwordless authentication via the LastPass MFA app?

The LastPass MFA app is an adaptive authentication solution that supports various forms of authentication, including biometrics (face or fingerprint recognition), as well as pattern matching/PIN Code. You can use this authenticator to verify your login for your LastPass Vault (if you have one) and/or websites that you sign in to and use daily.

Note: This feature requires an account with the LastPass Business + Advanced MFA add-on. How do I upgrade my LastPass Business account with an add-on?
Note: Feature availability within the app may vary depending on the settings configured by your LastPass admin and/or whether you have migrated from the LastPass MFA app to the LastPass Authenticator app. Learn more about this app migration

Step #1: Activate passwordless authentication

Step #2: Set up and configure in LastPass

Once activated, you can enable the LastPass MFA app to be used to protect your LastPass Business account.
