E-num Auth
E-num is an up-to-date authorization system that provides enhanced information security through cryptography.
- Sign-in and action confirmation A request arrives as a push or a QR code, or you enter it by hand; the app computes the response value and sends it to the site.
- One-time codes Two-factor (2FA) sign-in codes for GitHub, Google and other services, like Google Authenticator but inside E-num.
- Passkeys Passwordless sign-in to websites: the key stays in E-num, and you confirm with your PIN or biometrics.
