TOTP 2FA Token Generator
Generate standard 6-digit Time-based One-time Passwords (TOTP) used for Google Authenticator 2FA. Runs completely locally on your browser.
* The secret key is typically provided by services when enabling 2FA. We use standard 30-second cycles and SHA-1 hashing algorithm.
Frequently Asked Questions
A Time-based One-time Password (TOTP) calculator generates temporary 6-digit codes used for two-factor authentication (2FA). It uses a shared secret key and the current time to compute unique codes that change every 30 seconds.
Yes! This calculator runs 100% locally in your browser using client-side JavaScript. Your shared secret keys are never uploaded to any server, ensuring complete confidentiality of your 2FA keys.
TOTP tokens are aligned with Unix time intervals of 30 seconds. The progress bar displays the remaining validity time of the current code. Once the timer reaches zero, a new code is automatically generated.
