What am I missing with passkeys?

As ianto mentioned in their very good comment, we're currently at the beginning of a long transition period and passkeys will become more intuitive and standardized across the industry as time goes on.

For the moment, many websites don't offer the ability to fully remove your password after adding a passkey so you'll be able to sign in using either your passkey or your password in most places. Continue to follow best practices and make sure that all of your passwords are strong and unique: Use the password generator to change and strengthen your passwords

Part of the reason why many services leave passwords as a fallback option is because passkeys are not yet supported across all devices yet.

1Password warns folks when a password has been reused or should be made stronger, whether you're using a passkey or not: Use Watchtower to find account details you need to change
