alt Hacker News> What’s important to know is that unlike with any other kind of login credential, you do not have ultimate control over your passkeys.
Use proper password managers, like keepassxc. Then you have control. But problem is that not all sites support that. If you can't use the above - then yes, passkeys are bad, especially if they become mandatory.
If you keep reading the article, you’ll see that the claim is current (unattested) passkeys are a stepping stone to “attested passkeys”. Attested passkeys would require remote attestation with OS, TPM, and password manager all working together, and would allow websites to require things like hardware backed non transferable passkeys that you don’t control. This has always been my suspicion and I do think it’s worth worrying about.
