Most apps on your iPhone or Android device can be easily deleted and reinstalled. This is a fairly common practice if you switch between devices often, but in the case of WhatsApp, simply reinstalling the app isn’t enough.

When you install a new version of WhatsApp on a device, you will need to log in with your phone number and then go through another layer of security, two-step verification, to regain access to your WhatsApp account. This extra layer of security protects your account if your SIM card is stolen, so that no one but you can access your WhatsApp profile later.

In this post, we will explain what WhatsApp's two-step verification option is and how you can reset it on your device.

WhatsApp doesn’t let you have a password to log into your account. However, to protect your account from malicious login attempts, the service offers a two-step verification feature. This optional feature lets you add an extra layer of security to your WhatsApp account by setting a six-digit numeric PIN that will allow you to access your account if WhatsApp is uninstalled from your device.
