CLIENT-SIDE AUTHENTICATOR

Your next code. Right here.

Generate TOTP codes from a Base32 secret or an otpauth://totp URI. Uses your device clock and Web Crypto; the secret never leaves this tab.

An otpauth URI supplies its own supported settings. HOTP counter-based URIs are not supported.

This utility generates codes for an existing secret. It does not enable 2FA on your Mailread login. Clipboard contents may remain after clearing this page.
