With security concerns rising over private chat messages, it’s best to protect your WhatsApp account. iPhone users have been able to protect their conversation with face unlock for quite some time, but there is no native implementation for Android devices. Until now, that is. WhatsApp has enabled the option for Android users to protect their chats via fingerprint authentication and it’s very easy to implement. Here’s our handy guide that will show you how to protect your WhatsApp chat from unauthorised access with your fingerprint.

Open WhatsApp and click the three dots on the left side next to the search icon.
Go to Account

You can also select if you want to lock WhatsApp immediately or after 1 minute or 30 minutes. That’s it, once done your WhatsApp messages are now secured and cannot be opened without your fingerprint access.
