Passkeys change the paradigm of how people are typically authenticating online today by replacing the password with an unphishable primary factor for user authentication that is built into virtually every modern computing device today." "Unlike passwords, passkeys do not rely on human-readable shared secrets that are highly susceptible to attack and easy to bypass. "There is a fundamental difference between passwords, which are human-readable “secrets” transmitted over the internet, and passkeys, which are a possession-based authentication method leveraging advanced cryptography.

He explained that the main difference between the two is that unlike passkeys, passwords are easily readable by humans which makes them less secure, saying: Tom's Guide also spoke with Andrew Shikiar, the executive director and CMO of the FIDO Alliance, about passwords and passkeys. However, as passwords become more complex, people have a more difficult time remembering them which is why both password reuse and using simple passwords like “ 123456” is such a common practice despite the security risks. Besides letters and numbers, you can also add different symbols to your passwords to make them harder to guess. Passwords can be short or long with the latter being more secure.
