Create a free QR code for your Facebook page or profile. Also, learn how to configure Facebook 2-Factor Authentication (2FA) Code Generator with standard authenticators.
This premium resource addresses two main tasks: generating a dynamic or static **Facebook Profile/Page QR Link** to grow your social audience, and configuring secure **Two-Factor Authentication (2FA)** following Meta's retirement of the legacy in-app Code Generator.
In 2023, Meta retired the legacy built-in "Code Generator" from the Facebook mobile application. Facebook now secures account logins using standard Time-based One-Time Passwords (TOTP) compliant with RFC 6238. This allows you to generate secure login verification codes on your device using standard third-party authenticator applications.
The internal Facebook App menu generated verification codes. This was bound only to your Facebook mobile app session, presenting reliability issues if the app crashed or you logged out.
An independent external app (e.g. Google Authenticator) parses an industry-standard 2FA secret QR code locally, generating highly secure 6-digit codes every 30 seconds without internet dependencies.
Navigate to Facebook *Settings & Privacy* > *Accounts Center* > *Password and security*.
Click *Two-factor authentication*, choose your profile, and select **Authentication App**.
Facebook will display a setup QR code. Scan this code inside Google Authenticator, Duo, or 1Password.
Enter the generated 6-digit verification code back into Facebook to lock in your authentication app.
Select 'Facebook' from the social menu.
Enter your Facebook Page or Profile URL.
Click 'Generate' to create the QR code.
Download the image and place it on your marketing materials.
A standard Facebook Link QR Code embeds the URI payload directly within a 2D matrix structure. Modern scanners leverage high error-correction levels (up to 30% pixel block damage recovery) to successfully open deep-links directly in the native Facebook app on iOS and Android.
For commercial deployments, always configure high contrast and minimum dimensions of 2cm x 2cm to guarantee instantaneous barcode reading by all standard device sensors.
ISO standards, error correction science, scan failure diagnosis, and format compliance — everything needed to deploy QR codes that work everywhere.
QR codes are the dominant 2D standard for consumer applications, but competing formats exist for specialized industrial and government use cases.

QR codes use Reed-Solomon coding — the same algorithm used in CDs, DVDs, and deep-space communication. It works by adding redundant data polynomials to the message. When a scanner reads a damaged code, it solves the polynomial equations to reconstruct missing data without retransmission. Level H adds 30% redundancy, allowing full recovery from a code that is up to 30% physically destroyed.
The three square "eyes" in the corners of a QR code are called Finder Patterns. They allow the scanner to identify the code orientation and perspective distortion in milliseconds, enabling reliable scanning from any angle up to 360°. The alternating black/white strips connecting them are Timing Patterns that establish the module grid coordinate system for pixel-precise data extraction.
