App Lock - Fingerprint Lock

App Lock - Fingerprint Lock is a privacy-focused Chrome extension that lets you secure private apps with a password, PIN, or fingerprint. It works on-device, protecting your data without uploading anything to the cloud. Lock multiple apps (Facebook, Messenger, Instagram, and more) and customize how they appear for discreet security.

Features include intruder selfies when a wrong pass is entered, random keyboard rearrangement to prevent peeking, and flexible relock timing. You can lock new apps automatically (optional Usage Access), hide the unlock path, and choose from several lock methods and themes. All lock settings stay locally on your device, and no personal information is read or shared.
