#backuppasskeys — Public Fediverse posts

@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.
