About
2FA HashNode is a free, privacy-focused two-factor authentication code generator. Your secret keys never leave your browser — there's no server, no account, and no tracking. It works fully offline and is compatible with any service that supports RFC 6238 TOTP, including Google, GitHub, and Dropbox. All codes are generated using your browser's built-in Web Crypto API — open, auditable, and free.
How It Works

Enter Your Secret Key

02
Automatic Code Generation
A new 6-digit code is generated every 30 seconds using the TOTP standard.
03
Use Your Code
Click to copy the code and paste it into your login form. Codes refresh automatically.
