⏱️ Time-based One-Time Password (TOTP) Emulator

Emulate a Time-based One-Time Password (TOTP) from a secret key.

Time-based One-Time Password (TOTP) Emulator

A Time-based One-Time Password (TOTP) is a temporary passcode generated by an algorithm that uses the current time as one of its factors. This tool emulates a TOTP from a secret key.

Usage

  1. Scan or upload a QR code that contains a secret key.
  2. The TOTP will be displayed.
  3. Click the TOTP to copy it to the clipboard.

Configuration

You can change the secret, the period, the number of digits, and the algorithm. The changes will be reflected immediately.

However, since the configuration differs from the server-side, the TOTP may not match.
