What's two-factor authentication? How do I use it?

Two-factor authentication is a security feature. When two-factor authentication is on, every time you log into Instagram from an unknown device you'll be asked to enter an SMS security code or backup code in addition to your username and password.

To turn two-factor authentication on:

  1. Go to your profile and tap (iOS) or (Android) in the top-right corner
  2. Scroll down and tap Two-Factor Authentication
  3. Tap Require Security Code to move to the on position
  4. If your account doesn't have a confirmed phone number, you'll be asked to enter a phone number. After entering the phone number, tap Next.
  5. A code will be sent to you. Enter that code and tap Next.

Note: After you've turned on two-factor authentication, you'll be able to access backup codes for your account. If you don't receive an SMS security code during the two-factor authentication login process, you'll still be able to log into your account by using a backup code. Learn more about backup codes.

To turn two-factor authentication off:

  1. Go to your profile and tap (iOS) or (Android) in the top-right corner
  2. Scroll down and tap Two-Factor Authentication
  3. Tap Require Security Code to move to the off position
  4. Then tap Turn Off at the bottom of the message that appears

Keep in mind that you must have a confirmed telephone number for your Instagram account to use two-factor authentication. When you enter a telephone number to turn on two-factor authentication it will become the confirmed number for your account.
