I don't have a smartphone, how can I use multifactor authentication with LastPass?

LastPass supports multifactor authentication in various forms that do not require a smartphone.

The following multifactor options are supported:

Set Up LastPass to Use the LastPass Authenticator app (phone call or YubiKey)
Use Duo Security Authentication (phone call or security key)
Use YubiKey Multifactor Authentication (security key)

Restriction: If you have a LastPass Teams or LastPass Business account, the ability to perform these actions may be limited or prohibited due to policies enabled by your LastPass admin.
