How do I use LastPass with Windows biometric framework (WBF)?
You need to first use your fingerprint software to enroll one or more fingers.
After doing so, you can go to your LastPass Icon > My Vault > Account Settings > Multifactor Options and setup fingerprint authentication from there.
Please note that fingerprint authentication continues to be tested and improved, and that not all devices are supported at this time.
