How to lock WhatsApp on your phone for both Android and iPhone?


We use WhatsApp for communicating, and one of the promises the company makes is to keep everything secured between the two parties. However, if you want to take data protection a notch up, then here is how you can lock WhatsApp on phone -Android and iPhone both!

End-to-end encryption and two-factor authentication

WhatsApp uses end-to-end encryption and two-factor authentication to ensure that everything you communicate is secure, whether it’s texts, chats, or video calls. To give an extra layer of security you can also enable app security from your device’s settings using face ID, biometrics, and other methods. This ensures that no one can access your WhatsApp without your permission, even if your phone is available to others. WhatsApp is also accessible for desktop computers, in addition to mobile devices. The issue is that WhatsApp does not automatically lock when you close it. It takes a few times to get locked. In the meanwhile, anyone with access to your phone can read your WhatsApp messages. There are ways to password protect WhatsApp on Android or iOS.

Enable 2-step verification on Android

You can enable the two-step verification for WhatsApp on your Android. This is incredibly simple to do and takes very little time. You can enable this feature without needing third-party software because it is an intrinsic feature of WhatsApp. Here is how to enable 2-step verification on WhatsApp for Android.

  • Open WhatsApp on your mobile.
  • Click on the three-dotted button, then select Settings.

WhatsApp is a messaging app that takes security very seriously. End-to-end encryption is used for all texts, chats, and video calls. So, you can rest assured that nothing you say or do on WhatsApp will be intercepted or monitored. Even with the end-to-end encryption, you can add the two-step verification code to protect your privacy and lock WhatsApp on your phone. However, you can make WhatsApp even safer by using biometric security such as fingerprints or Face ID, to protect the app itself. This way, even if your phone is stolen, your WhatsApp communications will be safe. You can do this on WhatsApp itself without downloading any third-party app.
