In Catalina, Can Fingerprint Replace Password Requests on Preference

Solution 1:

Yes, you can replace a password request on System Preference with Fingerprint also.

You can also use Touch ID to unlock these features on your Mac:

• Password-protected Notes

• The Passwords section in Safari preferences

• System Preferences

Note: If you have FileVault turned on, you must type your password to unlock the Security & Privacy pane and the Users & Groups pane.

• Just make sure that you have enabled all the checkboxes to select the Touch ID features that you want to use on your Mac.
