LastPass MFA Setup: A Step-by-Step Guide

When setting up LastPass on your new phone, you may encounter the requirement to authenticate using Two-Factor Authentication (2FA). This is a normal process that ensures the security of your account.

To start with, you'll need to install LastPass Authenticator first. However, you might be surprised to find out that it won't work unless you've installed Last Pass itself. So, go ahead and download Last Pass on your new device.

Once you've completed the installation process, you will receive a notification requesting 2FA authentication. Don't worry if you didn't receive a push notification; requests may still appear on this screen.

To refresh for new requests, simply pull down on the list. You can also approve or deny login requests from within the app by tapping Security and then Login Requests. If you haven't already, you can opt into this feature by clicking 'Request a code sent to your phone via text message' when logging in to your account.

In some cases, you may receive a login code via SMS text message as well. Once you approve the login request, you'll be immediately logged in to your account.

When using Twitter for iOS, Twitter for Android, or other devices, a push notification may be sent to your phone requesting authentication. If you enrolled in login verification before March 21, 2016, you can use security keys as your sole authentication method without enabling any additional methods.

Lastly, if you add a security key for extra protection, we no longer require using another backup method for added security. With these steps, you'll be well on your way to setting up LastPass MFA and keeping your account secure.
