  • Akamai MFA for SSH Logins
    I used this when it was still Krypton [0], it worked very well, it just gives you a "Want to log in?" notification on your phone, but for almost anything imaginable (inc SSH). I don't see it used much though. [0] https://krypt.co/. - Source: Hacker News / over 1 year ago
  • Using your SIM card for MFA when logging in to an SSH server
    Using your SIM card for MFA when logging in to an SSH server (through paid API requests to a third party) There are ways to use your phone's secure storage capabilities for key storage. I've dabbled with using Krypt.co [1] for this, though that's sadly been deprecated and will at some point be replaced by a paid-for cloud service from Akamai. I'm sure there are other options available as well. A far superior... - Source: Hacker News / over 1 year ago

    Krypton (https://krypt.co), now owned by Akamai (https://akamai.com/mfa) who removed one of the best features, IMO (SSH key on a phone...) does this to an extent... Akamai says it's FIDO2... Have not used it in a while... It is free though until Akamai decides not to give it away... - Source: Hacker News / about 2 years ago

Funnily enough, a system for signing web... - Source: Hacker News / about 2 years ago
  • Real Problems That Web3 Solves, Part 1
    > For the purpose of login in with a private key, I would prefer some browser extension (or built in the browser) that generates a key from a seed (like a crypto wallet) and only does that.
