What is WhatsApp Lock and 2FA?

Apart from standard features like blocking contacts, both the lock and 2FA features contribute to a pleasant WhatsApp experience and your privacy. The WhatsApp Lock feature is essentially a biometric security option you can use that enables finger or face scanning. This means that whenever you open the WhatsApp app for the first time, you will need to scan your finger or face to enter depending on what you enabled. This privacy measure ensures that only you are accessing your WhatsApp account and works as an additional layer of protection.

Furthermore, two-factor authentication works similarly and also adds a layer of protection to your WhatsApp logins. Once you enable it you will enter a 6-digit code. From then on, whenever you are registering your phone number with WhatsApp this 6-digit PIN will be required. Make sure you choose something that you can easily remember but other than that this feature guarantees maximum security.

Depending on your phone’s interface, these options might be located in different menus like Privacy, Security, or the Account menu. If your layout differs from our tutorial, fear not, the options are still there just browse around and you will find them easily. Let us take a look at how you can enable these two safety features.

By design, WhatsApp cannot access your biometric information like your fingerprint because the information is stored entirely on your phone. Your data is completely safe.

Final Remarks

Whether you enable the WhatsApp Lock, the 2FA feature or both, your app security will benefit greatly from them.
