Analogy/Comparison

Using a passkey is like having a special digital key on your phone that only works with your finger or face, letting you into websites without needing to type a password.


Why It Matters

Passkeys make logging into online accounts much safer because they are very hard for hackers to steal. For example, passkeys protect you from phishing scams, where someone tries to trick you into giving away your login details, making your online life more secure.
