Description
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.

2 ★ I have the app installed and its 2.5.5 but I don't see the team tab If I can get this fixed then I will change my review. I'm trying to get my servers set up with this, but 'creating a team' is not yet supported through the command line, and it doesn't show on the app like it says in the command line output
5 ★ This is a fantastic use of Android phones that meet the requirements to be a FIDO hardware authentication token. The fact that I can use it for my ssh sessions with the kr package is also amazing.
2 ★ I don't understand how to use it, I've installed ff extension and this app. It says that I need to visit krypt.co/start page, then redirects me to gitlab, which generates qr code and suggests to download Google Authenticator. do I really need to download more Authenticators to make this work?
3 ★ Cannot add sites that aren't supported by the app. I don't like using two authentication apps, so I'll just stick to using Authy.
4 ★ 4 stars only because the app has to fully open to accept the notification
1 ★ I really love the idea but it simply didn't work. It never registered as a u2f token on any site I tried
4 ★ Not reliable as hardware 2FA, but good alternate because cheap. My question: How to migrate data because I want to change smartphone?
5 ★ magic for secure key management for SSH keys and codesigning. Pretty cool for U2F, too.
5 ★ An excellent solution for U2F and Fido.
5 ★ lil tech savvy needed but is Defff worth the effort!!!
1 ★ Broken.
5 ★ great job mate
4 ★ If I enable "Developer Mode" along with "One-Touch U2F Login option off", then the logins get stuck and never seem to get approval from the Mobile Phone. It works as intended once I turn off the developer mode.
5 ★ Love it, save yourself some cash by not having to buy multiple hardware keys. You can use this and a Yubikey to advance protect your Google account.
1 ★ Pairing with sites doesn't work
