Multifactor authentication refers to a device that can be enabled for use with your LastPass account, and requires a second step before you can gain access to your account. Multifactor authentication devices help protect your account from keyloggers and other threats – even if your Master Password were captured, someone would be unable to gain access to your account without this second form of authentication.

To enable Multifactor Authentication, go to the LastPass Vault > Account Settings > Multifactor Options.  Detailed instructions for each Multifactor Option is provided below.
