Generate Time-based One-Time Passwords (TOTP) for two-factor authentication. Works completely offline — your secret keys never leave your browser.
Your secret keys never leave your browser. All TOTP codes are generated locally on your device.
Works without internet. No data ever leaves your browser.
Codes refresh automatically every 30 seconds per TOTP standard.
Compatible with Google Authenticator, Authy, and all 2FA apps.
A TOTP (Time-based One-Time Password) Generator creates temporary 6-digit codes that refresh every 30 seconds. These codes are used for two-factor authentication (2FA) to add an extra layer of security to your online accounts, alongside your regular password.
Our generator works entirely in your browser using the RFC 6238 standard — the same algorithm used by Google Authenticator, Authy, and Microsoft Authenticator. Your secret keys are never sent to any server, ensuring complete privacy and security. Simply enter the Base32 secret key provided when setting up 2FA on any website.
