Krypton makes authentication easy and secure for developers

 

• No more passwords or codes
  
• Zero touch logins
  
• Immune to phishing
  
• Securely stores your U2F, SSH, & Git-signing private keys on your phone
  

Krypton makes strong public key authentication easy to use by securely storing your private key on your phone. The private key never leaves your device.

 

1. Web two-factor U2F security key
   
2. Login into servers with SSH
   
3. Sign Git commits and Tags (PGP)
   

Supports the sites you love

Krypton is a security key that is fully compatible with FIDO U2F. It works with the sites you love: Facebook, Google, Dropbox, Stripe, GitHub, BitBucket, GitLab, Salesforce, and many more. Get started by pairing Krypton with your browser by downloading our browser extension at: https://krypt.co/start.

 

Works with OpenSSH

Download our command line utility curl https://krypt.co/kr | sh and type kr pair to securely pair Krypton with your computer. Krypton integrates with the ssh command to send signature requests right to your phone.

 

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 U2F - Krypton implements the standardized FIDO Universal 2nd Factor (U2F) protocol to provide secure, un-phishable two-factor authentication on the web, now in the convenient form factor that is your phone.
  End-to-end Secure
  
• Zero Trust - Krypton is built on top of an end-to-end verified and encrypted architecture. This means zero trust. We, Krypt.co, have zero information about keys or where you're authenticating. The keys only live in the Krypton app on your phone.
  

All of the source code can be found at github.com/kryptco.

Sounds a bit like a passkey.

Yes, very similar to a passkey, however with passkeys this also applies to devices running windows.
