Password managers such as Bitwarden and KeepassXC support creating and using Passkeys for accounts.

Presumably, you are already using a password manager at this point. Memorizing dozens of account passwords is not suitable for maintaining strong passwords.

Also, passwords still exist as a fall back if you need it, such as a situation you don’t have your device available. And not all accounts have to use passkeys.

Passkeys are effectively like ssh keys. Do ssh keys “lock you down” to specific devices? Sure they absolutely do unless you generate more keys or have some key management/sync workflow.
