How to use this OTP generator

  1. Paste the Base32 secret key shown when you set up 2FA (often shown as text next to a QR code).
  2. A 6-digit code generates instantly and refreshes every 30 seconds.
  3. Use it exactly like you would a code from Google Authenticator or similar apps.

How does TOTP work?

Time-based One-Time Password combines a shared secret key with the current time (rounded to a 30-second window) using HMAC-SHA1, producing a 6-digit code that both you and the server can compute independently without any network communication.

Is it safe to paste my 2FA secret into a website?

Everything here runs locally in your browser and the secret is never transmitted anywhere, but as a general habit, only paste 2FA secrets into tools you trust and understand — this one included.

Why doesn't the code match my authenticator app?

This usually means your device's clock is out of sync — TOTP relies on both sides having accurate time within a small tolerance window, so check your system clock if codes consistently mismatch.
