Great features. Everything works as advertised. But first time experience is so bad. Have you ever done any user testing? I had to rely on a friend of mine to help me setup this app. He is long time user so he helped a lot. Please consider some user testing when your user is given your homepage and they need to set up everything from websites to SSH. You will know immediately what I'm talking about.

Failed to work with GitHub; now locked out. Have not managed to get the app to work with other websites' 2FA systems, either. Avoid like the plague.

Great, easy to use two factor authentication solution. Doesn't quite work for GitHub and advertised, but works very well on other services I have used it with, including ssh for my VPS. Wish it worked with more services out of the box.

i liked the fact i can confirm a logon request but if my phone is locked when the prompt comes up, i would expect the prompt to still be there when i unlock my phone, its not. also pairing failed when i used my fingerprint, but the fingerprint icon is on the pairing screen. so too clunky for me, but i love the concept

Does what it says. Great as a second or backup U2F token. You always want to have at least two U2F keys enrolled on your accounts so as not to be locked out of your accounts by losing your only key... Install the Krypton browser plugin on the desktop browser, install the phone app, then enroll your phone as a U2F key for the website you want to authenticate on. I find Krypton is usually more convenient than using the Yubikey on my keyring as my phone is usually closer to hand than my keys.

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

About this app

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.
