What Is a 2FA Backup Code Generator?
Two‑factor authentication (2FA) adds an extra layer of security to user accounts. Backup codes — sometimes called recovery codes — are a fallback method for users who lose access to their primary 2FA device (like an authenticator app). This utility generates a set of cryptographically secure, one‑time‑use codes that can be stored safely and used to regain account access. It's an essential component for any application implementing 2FA.
How to Use
- Choose your settings — select the number of codes (1–50), code length (6–16), and format (alphanumeric, numeric, hex, or Base32).
- Click "Generate Codes" — the tool will create a fresh set of backup codes using cryptographically secure randomness.
- Copy or save the codes — use the "Copy All" button to copy the codes to your clipboard, or manually copy them to a secure location. Treat these like passwords — they grant access to an account.
Frequently Asked Questions
Are the generated codes truly random and secure?
Yes. The tool uses the Web Crypto API's crypto.getRandomValues() — a cryptographically secure pseudorandom number generator (CSPRNG) built into modern browsers. The codes are suitable for use in production 2FA systems.
Does this tool store or transmit my codes?
No. Everything runs entirely in your browser. The codes are never sent to any server, stored in cookies, or logged. Once you close the page, the codes are gone unless you've saved them elsewhere.
Can I use this in my own application?
Absolutely. The source code is available for purchase through the link above. It's a single, self‑contained HTML file that you can integrate into your project or resell as part of your own toolset.
