Open the Instagram app, go to your profile, tap the menu icon, select Settings and privacy, then navigate to Security and choose Two-Factor Authentication. 2. Select your preferred 2FA method: use SMS to receive login codes via text message or choose an authentication app like Google Authenticator to scan a QR code and generate time-based codes. 3. Generate and securely save 10 backup codes to use in case you lose access to your phone or authenticator app. 4. Confirm your setup, ensuring your device’s time is accurate if using an authentication app, after which 2FA will be enabled with a confirmation message. Enabling 2FA protects your account from unauthorized access even if your password is compromised, adds an extra security layer, and safeguards your personal content by requiring a second verification step only when logging in from new devices or browsers, making your Instagram account significantly more secure.

How to set up two-factor authentication on Instagram

Setting up two-factor authentication (2FA) on Instagram is a simple but effective way to protect your account from unauthorized access. Here’s how to do it step by step.

How to set up two-factor authentication on Instagram

1. Open Instagram Settings

First, open the Instagram app and go to your profile by tapping the profile icon in the bottom right. Then, tap the three-line menu (hamburger icon) in the top right corner. Scroll down and select Settings and privacy.

In the Settings menu, look for Security and tap on it. Under the Security section, find and tap Two-Factor Authentication.

3. Choose Your 2FA Method

Instagram offers a few options for two-factor authentication:

  • Text Message (SMS)
    Tap Authentication with phone number, then select your phone number. Instagram will send a code via SMS each time someone logs in from a new device.

  • Authentication App (Recommended)
    Tap Authentication app, then follow the prompts to link your Instagram account with an authenticator app like Google Authenticator, Microsoft Authenticator, or Authy. You’ll scan a QR code and enter the generated code to verify.

  • Backup Codes
    After enabling either method, you can generate 10 backup codes. Save these in a safe place—they let you log in if you lose access to your phone or authenticator app.

4. Confirm and Enable

Once you’ve set up your preferred method, 2FA will be automatically enabled. You’ll see a checkmark or confirmation message.

Note: If you use the authentication app method, make sure your device’s time is correct—time-based codes won’t work if your clock is off.

Why It Matters

  • Prevents unauthorized logins even if your password is compromised
  • Adds an extra layer beyond just a password
  • Helps secure your personal content and messages

You’ll be prompted for the second factor only when logging in from a new device or browser, not every time you open the app.

That’s it—your Instagram account is now more secure. Just remember to keep your backup codes safe and update your phone number in settings if it changes.
