Who wants prying eyes to go through your Whatsapp messages, whether it is family or friends? In these times of protecting privacy, Whatsapp has introduced a built-in fingerprint lock on the app. Once enabled, Whatsapp can be started only when you scan your fingerprint – no passwords to remember!
Make sure you have the latest version of Whatsapp downloaded from the Play Store and you have a fingerprint scanner enabled on your phone. Just go to Whatsapp Menu, Settings, Account, Privacy and look for Fingerprint Lock at the bottom. Just enable the Fingerprint Lock and you are done!
Now, you have full security and the confidence that Whatsapp will be started only when you scan your fingerprint!
