What is two-factor authentication?


Two-factor authentication increases security by asking a user to provide not only their password, but also more proof that they are who they say they are. There are lots of forms of two-factor authentication, such as a code texted to a phone, a code generated from an app or a fingerprint.

LastPass integrates with many two-factor authentication options so users can protect their vault with extra security.

How does it work?

Two-factor authentication is the addition of a second login step. Normally when you log in to an account, you provide a username and password. When two-factor authentication is enabled, you also must provide that additional information before you're given access to the account.

After two-factor authentication is enabled for your LastPass account, you'll be prompted to complete a step after you enter your master password. The action required will depend on what two-factor authentication option you selected and typically takes no more than a few seconds to complete. You can also mark specific devices as trusted so that you don't have to re-enter your two-factor authentication on those devices, while still enjoying the protection of two-factor authentication for your account.


Do I need two-factor authentication?

We strongly recommend turning on two-factor authentication for your LastPass account. In the unlikely event that someone steals your master password, two-factor authentication will stop them from being able to log in to your account. Because an attacker wouldn't have access to your two-factor authentication, they wouldn't be able to access your vault.
