About WhatsApp
One of the most downloaded applications worldwide is WhatsApp, the application has about 1.5 billion active users in the world who not only send text messages, but also stickers, GIFs, videos, documents, etc.
The conversations we have on WhatsApp are usually private and not shared with the world. However, no one is safe from spies.
When we lend our phone to someone, the chats stored in your WhatsApp may be read if they are not protected.
In order to improve the level of security in the quick messaging application, there are tools that will help you lock your chats. These are developed by third-party companies that will only help you put a lock on all your conversations.
The first one is Norton App Lock and it is an app that has the feature of locking WhatsApp and unlocking it with just your fingerprint.
You just have to search for it in the Google Store, Google Play, and install it. It is completely free and does not have annoying advertising.
There is also Chatlock which, unlike the previous one, also offers you the option to unlock WhatsApp using a password or security pin.
Don't want anyone to see your photos? It is worth mentioning that WhatsApp also has its own system to hide files, such as the images you receive through your conversations.
To access it, simply go to Settings, then to Chats, and unlock the button for Visibility of media files. With this, the WhatsApp gallery will disappear from your smartphone's camera roll.
