Krypton Authenticator
By krypt co
Let's make authentication 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.
- Stops Phishing
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
Google, Facebook, Twitter, Dropbox, GitHub and many more.
- Quickly protect your accounts
Setting up two-factor can be time consuming and repetitive. Just scan once with Krypton.
Get started by pairing Krypton with your browser by downloading our browser extension at: https://krypt.co/start.
Are you a developer?
Krypton supports developer mode so you can use Krypton as a security key for SSH and PGP private keys in addition to U2F.
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. Krypton also makes signing Git commits and tags with PGP easy: run `kr codesign` to get started.
Unbeatable Security
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.
The source code can be found at github.com/kryptco.
