Nowadays, mobile devices such as cell phones have different security measures. This also includes fingerprint security, where a sensor scans our fingerprint not only to unlock the phone, but also to confirm many other actions that require additional protection. WhatsApp is one of the apps that we can protect with a fingerprint. This requires a simple configuration so that only you can access the content of the app with your fingerprint.
How to set fingerprint to lock whatsapp chats
To the fingerprint protection to apply to WhatsApp, first open the app and tap on the menu (in the top right corner of the screen):
WhatsApp main view
Then tap Settings or settings:
In this menu you click on Account:
Click below Account on Privacy or. privacy:
WhatsApp account settings
Now scroll down and click on the fingerprint lock in Fingerprint lock:
WhatsApp privacy settings
Next, click on the slider Unlock with fingerprint (unlock with fingerprint control):
Activate WhatsApp fingerprint protection
When we activate it, it changes from gray to a light green. The app will ask us to confirm our fingerprint to configure it:
If you haven’t configured your fingerprint, WhatsApp itself gives you the tools to do so in the form of a pop-up window with a notification and an option to configure it at that moment. If your terminal does not have a fingerprint sensor, it is of course of little use to make these settings.
You can also adjust how long it takes for the fingerprint protection to be triggered and finally you can enable or disable whether you want to receive a preview of the people who want to communicate with you and the message they are sending:
Fingerprint protection enabled
This method was first implemented on iOS but came to Android soon after. When you add this little safeguard, you make sure that no one but you can snoop into your conversations, so prying eyes are no longer a problem. If you haven’t already done so with your WhatsApp, we recommend you do so.
