In a digital world where dangers online change daily, having only a robust password is not enough. That’s where two-factor authentication (2FA) plays a role, an effective method that provides a second layer of security to your Facebook and Instagram accounts.
If you’re locking down a private profile or business page, enabling 2FA in 2025 is very crucial.

Two-factor authentication is a security measure for logging in that demands you to authenticate your identity through two different means: your password and another factor, such as a code sent to your phone. This guarantees that even in the case of a guessed password, the second form of verification will prevent them from accessing your account.
Facebook and Instagram both have 2FA to avoid unauthorized entry, notify you of something fishy, and protect sensitive data. If someone is trying to access your Facebook account, this is really helpful.

How to Enable Two-Factor Authentication on Facebook
Enabling 2FA on Facebook is easy. Follow these step-by-step instructions:
- Security Key (touch on a compatible device)
- Authentication App (such as Google Authenticator)
- Text Message (SMS)
Once configured, you’ll get login notifications when a person attempts to log in to your account from an unknown device or browser. You can also create 10 recovery codes for emergency use when your phone is not available.
Pro Tip: Don’t save your browser if you’re on public or shared computers.
Important Notes on Facebook 2FA Setup
If you have private browsing or your browser deletes cookies when you close, Facebook won’t keep track of your session, and you’ll have to type in a code every time.
You’ll need to have a mobile number associated with your Facebook to enable SMS authentication.
Facebook will prompt automatically to save the browser you are using — only accept if it is a personal trusted device.
Instagram Two-Factor Authentication for Multiple Devices
Instagram provides additional 2FA capabilities that allow you to connect a maximum of five devices to use for login verification through a third-party application.
How to Enable 2FA on Instagram
You will need to set up 2FA on your main device first before you connect others. Every device will have to have its own login authentication app.
Disconnecting Devices from Instagram Two-Factor Authentication
When a device is no longer needed for access, you can disconnect:
Note: Taking a device out of 2FA does not log it out from your Instagram account. Manually log it out for full security.
