Free Online 2FA Code Generator

Two factor authentication (2FA) is one of the most widely used security technologies on the internet today. Many modern platforms such as Instagram, Facebook, Google, Binance and Discord use two factor authentication to protect user accounts from unauthorized access. Instead of relying only on a password, 2FA adds an additional verification step using a temporary authentication code.

This generator uses the standard TOTP (Time-Based One-Time Password) algorithm defined in RFC 6238 - the same algorithm used by Google Authenticator, Authy, and every major platform's 2FA system.

Unlike typical online 2FA tools, every calculation here happens directly in your own browser using the Web Crypto API - your secret key is never transmitted to, or stored on, our servers, and nothing is remembered between submissions. Paste your secret and submit any time you need a fresh code.
