My favourite bit from TFA: "So do yourself a favour. Get something like bitwarden or if you like self hosting get vaultwarden. Let it generate your passwords and manage them. If you really want passkeys, put them in a password manager you control. But don't use a platform controlled passkey store, and be very careful with security keys."
Join me next week when I have inevitably to point out storing authentication on a device people watch porn on the toilet on with is obviously also a bad move.
