About TOTP Generator
Paste a base32 secret or a full otpauth:// URI to generate live time-based one-time passwords, with a countdown to the next code rotation.
Codes are computed locally with Web Crypto HMAC-SHA1 per RFC 6238 — useful for testing 2FA flows or recovering codes, without sending secrets anywhere.
