WhatsApp is a messaging app that prides itself on security. All texts, chats, and video calls rely on end-to-end encryption so you can have confidence that nothing you do in WhatsApp can be intercepted or monitored.

It's possible to make WhatsApp even more secure, though, by protecting the app itself with whatever biometric security your phone has, such as fingerprints or Face ID. This way, even if someone gets physical possession of your phone, your WhatsApp messages will remain secure.

You can use your Android phone's fingerprint reader to ensure only you can open the app.
