"Search Assist:
A passkey is a digital credential that replaces traditional passwords, allowing users to sign in to apps and websites using biometrics like fingerprints or facial recognition, or a device PIN. Passkeys enhance security by being unique to each user and device, making them resistant to phishing and account takeovers."
Okay.
What's a device PIN?
"Search Assist:
A device PIN is a Personal Identification Number used to secure access to a device, such as a smartphone or computer. It typically consists of a numeric code that the user must enter to unlock the device and protect it from unauthorized access."
Okay. Why isn't a device PIN called a password?
