2FA Code Generator

Generate TOTP verification codes from a 2FA secret

Base32 secret or otpauth URI

Paste the secret from your account setup screen. Spaces and hyphens are ignored.

Waiting for secret

Enter a 2FA secret and submit to generate a code.

How it works

Paste a Base32 2FA secret or an otpauth:// setup URI, then submit to generate a standard 6-digit TOTP code. The code refreshes every 30 seconds.

  • Uses the browser Web Crypto API with HMAC-SHA1, matching standard authenticator apps
  • Runs entirely in your browser without storing or uploading the secret
  • Supports grouped secrets with spaces, hyphens, or padding characters
