5.Doing the Two-Step
Two-step verification is a must if you’re concerned about security. If you decide you want it on WhatsApp, you’ll have to enter a six-digit passcode when you use the app, but the inconvenience is worth the peace of mind. To enable it, go to Settings > Account > Two-Step Verification > Enable, and you’ll be asked to create a passcode. Make sure to also enter your email address when prompted so you can disable two-step verification if you ever forget your passcode.
