Enhancing Gmail Security: Implementing Two-Step Verification with Mobile OTP

Q. What is 2-step verification using mobile OTP ?

Two-step verification with mobile OTP is a security feature that requires both your password and a temporary, one-time code sent to your mobile phone via SMS for logging into your Gmail account.

Enabling two-step verification (also known as two-factor authentication):

  1. Go to your Google Account:
  2. Sign In:
    • If you’re not already signed in, sign in to your Google Account.
  3. Security Settings:
    • In the left-hand menu, select “Security”.
  4. 2-Step Verification:
    • Scroll down to the “Signing in to Google” section.
    • Click on “2-Step Verification”.
  5. Start the Setup Process:
    • Click “Get started”.
  6. Verify Your Password:
    • You’ll be prompted to enter your Google Account password.
  7. Phone Verification:
    • Enter your phone number. This is where you’ll receive your verification codes.
    • Choose whether you’d like to receive codes via text message or phone call.
    • Click “Next”.
  8. Verify the Code:
    • Enter the code you receive on your phone and click “Next”.
  9. Trust the Computer:
    • You can choose to trust the computer you’re using, so you won’t be prompted for a code on that specific device in the future (optional but recommended for personal devices).
  10. Turn On 2-Step Verification:
    • Click “Turn On”.
  11. Backup Codes (Optional):
    • Google will give you the option to download backup codes. These are useful if you can’t access your phone.
    • Keep these codes safe and don’t share them with anyone.
  12. Confirmation:
    • You’ll receive a confirmation that 2-Step Verification is turned on.
