Big Tech has implemented passkeys in a way that locks users into their platforms rather than providing universal security
Passkeys were developed to replace passwords for better account security, but their rollout by Apple and Google has limited their potential
Proton Pass offers passkeys that are universal, easy to use, and available to everyone for improved online security and privacy.

If the key is in the same device that's being used to access a protected resource over the network, the thing can be potentially be hacked and the key retrieved.

That's why there are solutions were the key never leaves a secure hardware device, such as challenge-response authentication were a bank card's smartchip is used to generate responses to the challenges (with the key never being outside the card) or keydongles that show a variable code, depending on time.

This is actually pretty old tech.
