Unbeatable Security

SSH

No more sensitive plain-text private keys floating around developer laptops, desktops, and servers. The private keys never leave your phone.

Web

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.

End-to-end Secure

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.
