@rmondello : what makes passkeys strong:

1. Software checks the domain name, which makes phishing hard;

2. Https is enforced, which helps prevent AitM attacks (unless Cloudflare et al. come into play);

3. A unique, long, unguessible, randomly generated "password" (public key) per account: dumb password rules and broken human RNG's no longer apply.

The rest is marketing (including the -hyped- asymmetric cryptography).

The "advantage" of denying the owner access to their own private keys hardly makes sense as long as session cookies are not device-bound.

The disadvantage of not being able to back up ones own private keys is the risk of vendor lock-in and the underestimated huge risk of account lockout [1]. And the latter leads to the necessity of being able to log in using weak authentication after the user loses access to their private keys.

PASSKEYS, HOE DAN EN WAAROM?

Zojuist heb ik geprobeerd om in https://security.nl/posting/929755 uit te leggen hoe passkeys werken, en wat de voor/nadelen zijn.

Boosten van deze toot wordt gewaardeerd!

Phishing is a very popular technique of attackers. They trick the user into entering their credentials on some fraudulent site pretending to be a corporate login page, for example to log into Microsoft Entra ID. The user enters their login credentials there and sends them to the attacker.
