Krypton Authenticator Editor's review

Let's make two-factor easy & secure. No more typing 6-digit codes. Zero touch two-factor logins on the web. Immunity to phishing.

Krypton implements the standardized FIDO Universal 2nd Factor (U2F) protocol to provide secure, unphishable two-factor authentication on the web, now in the convenient form factor that is your phone.

- Tired of typing 6-digit codes?

No more mistyping, missing 30 second windows, or waiting endlessly for that SMS.

- Instant Sign-in

Krypton securely pairs with your computer so that you don't have to touch your phone for each sign-in. Optionally, enable One tap sign-ins for enhanced security.
