A bug has surfaced in the app which allows anyone to get access to WhatsApp without going through Touch ID or Face ID.
A Reddit user de_X_ter has spotted the bug which only works when the user has selected the biometric authentication kick-in time to anything except 'Immediately', with the other options being 'after 1 minute', 'after 15 minutes', and 'after 1 hour'.
The bug activates when anyone tries to use WhatsApp share extension in any app except 'Immediately' in WhatsApp > Account > Privacy > Screen Lock.
Also, if one jumps to the home screen from the iOS Share screen, they can open WhatsApp without any interference from Touch ID or Face ID. It doesn't matter if you are way past the 1-minute, 15-minute, or 1-hour mark, which is set in WhatsApp screen lock.
