What Are Passkeys in Digital Security

The gist

Passkeys are a new way to log in online that replace passwords with a more secure and easier-to-use method based on cryptographic keys stored on your device.

Explain like I'm 5

Imagine instead of remembering a secret word to get into your clubhouse, you have a special magic key that only your clubhouse and you have, so no one else can sneak in.

Big picture

Passkeys aim to make online accounts safer by eliminating passwords, which can be stolen or guessed, reducing hacking risks and simplifying user experience across websites and apps.
