🔢 TOTP Code Generator

Generate and test time-based one-time passwords (2FA codes).

ℹ️ About TOTP Code Generator

The TOTP Code Generator is a utility for managing Time-based One-Time Passwords, the standard for **Two-Factor Authentication (2FA)**. It implements the algorithm used by apps like Google Authenticator, Authy, and Microsoft Authenticator.

By using a shared 'Base32 Secret', both your device and the server can generate the same 6-digit code every 30 seconds. This tool helps developers test their 2FA implementations or provides a way to generate a code if your physical device is unavailable.

📖 How to use TOTP Code Generator

  1. 1. To create a new 2FA setup, select 'Generate New Key'.
  2. 2. To generate a code for an existing account, paste your 'Base32 Secret' and select 'Get Current Code'.
  3. 3. The 'Provisioning URI' can be used to generate QR codes for easy scanning into mobile apps.

Frequently Asked Questions

What is Base32?

It is a 32-character alphabet used to encode the secret key in a human-readable way, avoiding ambiguous symbols like '0' and 'O'.

Is it safe to enter my secret here?

We do not store any keys. However, for maximum security, we recommend only using this tool for testing or with non-critical accounts.

Why does the code change?

The code is calculated based on the current time in 30-second increments. This ensures the code is 'one-time' and expires quickly.
