5. Not updating apps: App upgrades should be ignored since doing so exposes you to security flaws in the WhatsApp app. Ignoring updates might endanger your account since they frequently contain fixes for security holes that are known to exist.
6. Leaving devices unsecured: Failure to set a strong password, PIN, or biometric lock on your phone allows someone to physically access your WhatsApp account. This is especially dangerous in crowded spaces or if your phone is misplaced or stolen.
