Tired of typing 6-digit codes?
No more mistyping, missing 30 second windows, or waiting endlessly for that SMS.
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.
SMS and authenticator app codes can easily be phished. Don't let that happen to you. Krypton protects you from phishing.

Works with the sites you love
No more sensitive plain-text private keys floating around developer laptops, desktops, and servers. The private keys never leave your phone.
Krypton implements the standardized FIDO Universal 2nd Factor (U2F) protocol to provide secure, un-phishable two-factor authentication on the web, using just your phone.
Krypton is built on top of an end-to-end verified and encrypted architecture. This means zero trust. We, Krypt.co, cannot access your keys or see where you're authenticating. The keys only live in the Krypton app on your phone.
