What is TOTP?

TOTP (Time-based One-Time Password) is the algorithm behind apps like Google Authenticator, Authy, and Microsoft Authenticator. It generates a new 6-digit code every 30 seconds based on a shared secret key and the current time.

This tool helps developers test their 2FA implementations by generating valid secrets, creating scannable QR codes, and verifying codes work correctly.
