Analogy/Comparison

Using a passkey is like having a special, unstealable key on your phone that unlocks a specific door (your online account) without ever showing the key itself to anyone.


Why It Matters

Passkeys make logging in much safer and simpler because you don’t have to remember or type a password that could be stolen. For example, they protect you from phishing scams, where tricky fake websites try to get you to give up your login information.

The FIDO Alliance is a group of companies that created this technology. Phishing is when fake websites or emails try to trick you into giving away your login details. Biometrics means using parts of your body, like your fingerprint or face scan, to prove who you are. A private key is a secret digital code kept safely on your own device. A public key is a different code that gets sent to the website to confirm your identity.
