Description from store The Krypton Authenticator for Chrome is the companion to the Krypton app for iOS and Android. Krypton makes two-factor authentication easy and secure: - No more passwords or 6-digit codes - Zero touch logins - Immune to phishing 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. Get started in 3 steps: 1. Download Krypton for iOS or Android 2. Open the Krypton Authenticator chrome extension pop-up 3. Scan the QR code on the extension with Krypton ==Compatibility== It works with the sites you love like Facebook, Google, Twitter, Dropbox, Stripe, GitHub, BitBucket, GitLab, Salesforce, and many more. ==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. Learn more here: https://krypt.co.

  • (2020-09-20) Vince Marsters: Works ok on some sites but others give problems. Twitter for instance adds but can't complete as the verification notification never seems to get sent to the app. Also there is no way to back up the security accounts, so if the phone is lost or damaged then the keys go with it.
  • (2020-09-09) Subhrajyoti Das: No need to enter six digit codes anymore! Revolutionary idea.
  • (2020-04-14) Роман Кобаль: Not working with WebAuthn (based on specification). Tested on https://webauthn.io/ and https://demo.yubico.com/webauthn
  • (2020-01-13) I wish i knew about this amazing extension. The best
  • (2019-08-05) Louie: I normally do not write reviews but i found this very helpful. I did have to always input my codes and was always looking at buy a U2F device. This made my day!
  • (2019-05-24) Curtis Shimamoto: This makes hardware FIDO U2F keys extremely accessible to the average person. Just be sure to read through their amazing blog posts so that you can know how to ensure your phone is using the iPhone Secure Enclave or Android Keystore for all features that this has to offer. I'm especially impressed by the kr package that can be used with ssh, gpg, git, etc. Though for the parts it adds to your ssh_config, in order to make it only launch if kr can be found, I did change the first line from... Host * to... Match exec "test -x $(which kr 2>/dev/null)" Now it works perfectly! (I wonder how much Google is going to screw up the formating there? Probably all of it.)
  • (2018-09-11) Pinaki Gupta: Works Like a charm. Usually, I don't write reviews for the extensions on Google Chrome Webstore, but this extension compelled me to leave a review. I'm speechless. When you can use your phone as a U2F token, why should you buy a bunch of YubiKey or similar hardware keys to clutter your keychain and waste money, especially, in such a case when you have two or more spare phones laying around? Personally, I'd still go with a separate physical security key as a backup instead of relying on a spare phone, since the older Android devices are not updated by the manufacturers, and the OS itself is not absolutely leak-proof. The device we use quite frequently can be trusted upon, as we have control over such devices. Our primary devices can be relied upon, so using the device at hand as a U2F token wouldn't be a bad idea. This extension with its Android app has made me mesmerised.
