About

TOTP Generator produces the same rotating 6-digit codes as Google Authenticator or Authy from a base32 secret, following the standard RFC 6238 algorithm, useful for testing 2FA flows or getting a code without needing a phone in hand. It also parses otpauth:// setup URIs directly. The secret you enter is never transmitted; codes are generated entirely in your browser.
