WhatsApp is an increasingly versatile communication tool. We no longer use it only for trivial conversations, but also for business and personal matters. But no matter what purpose you use this platform for, you probably want to keep the content of your chats safe from prying eyes. Here are two ways to do it.

Secure WhatsApp with your fingerprint

First of all, we should make it clear that WhatsApp for Android does not let you set passwords to conversations. However, it does have the ability to protect access through certified biometric sensors.

To activate this function, enter the Account section of the preferences.

Next, open the privacy options.

In our test phone, we have a fingerprint reader. Therefore, the Fingerprint lock option appears. In specific models, it is possible to use facial recognition.

The next time you want to open WhatsApp, you will need to identify yourself with your fingerprint.

Secure WhatsApp with AppLocker

In case the previous solution does not suit you, AppLocker is a good alternative for you.

After installing it and granting the necessary permissions, create a lock pattern.

Go back to the list of applications and check that WhatsApp is blocked. If so, you will see a green padlock on the right side. Open WhatsApp to check that AppLocker prompts you for the pattern you set at the beginning.

This method is compatible with fingerprint reader verification. Therefore, it is possible to use AppLocker and at the same time ask WhatsApp to block access. In this way, you will achieve double the protection.
