You must set up your LastPass account and then download the Authenticator app. Setting up and using the LastPass Password Manager requires you to complete two separate sets of steps. The LastPass app is also TOTP compliant, meaning that it is compatible with all apps and websites that work with the Google Authenticator app and the Microsoft Authenticator app. It offers three different authentication methods: a six-digit time-sensitive passcode, a six-digit SMS code and a form of biometric authentication in the form of an automated push notification. Once you pair it with, say, your Facebook account, you’ll be able to add extra layers of security to it and make it that much more difficult for others to hack you. LastPass authentication prevents this from happening by adding up to three layers of additional authentication to the login process. If someone were to get a hold of your device under these conditions, they could potentially gain access to all of your accounts and personal data. Many people actually set their phones to remember their passwords to various places, making logins automatic. The motivation for using LastPass Authenticator is fairly obvious: security, security, security! Cybersecurity experts routinely recommend that everyone use a strong password when signing in to each and every account that they have online. Unlike simply using a password to sign into an account of yours, or even unlike the use of two factor authentication, the LastPass Authenticator App gives you an added layer of security by requiring multiple forms of authentication before you can login to any of the websites that you pair it with.

LastPass Authenticator is a multifactor authentication (MFA) password manager app that’s meant to be used on any Android, iOS or Windows mobile device.
