Fingerprint Unlock Not Working on Laptop

Security policies that affect Touch ID

For security reasons, you may be required to enter your password manually in these cases:

• You haven't logged in to your account since you last logged out, including by shutting down or restarting your Mac.
• You haven't unlocked your Mac in more than 48 hours.
• You’re changing Touch ID settings.
• Your fingerprint isn't recognized five times in a row.
• Your Mac is set up to log in automatically.
