Analogy/Comparison

Using a passkey is like using a special keycard to open a door with your fingerprint instead of needing to remember a specific combination for a lock.


Why It Matters

Passkeys are important because they make your online accounts much safer from hackers and make signing in faster. For example, they prevent common problems like phishing attacks where someone tries to trick you into giving away your login details, which happens often with regular passwords.

Jargon Conversion: A passkey is a new, safer way to sign into websites and apps using your face, fingerprint, or a PIN instead of a password. Phishing is when someone tries to trick you into giving them your login information. FIDO Alliance is a group that creates standards for logging in without passwords. Cryptographic key pairs are two linked digital codes, one for the website and one on your device, that work together to prove who you are.
