What's the Difference Between a Password, a Passcode, and a Passkey?

A password is a secret you type, a passcode is a short number that unlocks a device, and a passkey is a newer sign-in that uses your device instead of a remembered secret.

A password, a passcode, and a passkey all help keep your stuff safe, but in different ways.

What is a password? A password is a secret word or phrase you type to sign in to a website or app. It's usually longer than a passcode (like a sentence only you know).

What is a passcode? A passcode is a short number code, often 4 to 6 digits, used to unlock a phone, tablet, or other device.

What is a passkey? A passkey is a newer sign-in method that lets your device help prove it's you, using your fingerprint, face, or device lock. You don't need to remember or type a long password.

Think of it like this. A password is a secret phrase you remember. A passcode is a short lock code for your device. A passkey is a trusted helper key built into your device.

Where do you use them? Passwords: websites, school accounts, games, and apps. Passcodes: a phone, tablet, or smartwatch lock screen. Passkeys: newer sign-ins for apps and websites using your device.

Remember: a password is a secret thing you type, a passcode is a short code to unlock a device, and a passkey is a newer sign-in helper using your device. You've got this!

  • A password is a secret thing you type.
  • A passcode is a short code that unlocks a device.
  • A passkey is a newer sign-in that uses your device.

Three related but distinct things. A password is a memorized secret (word/phrase) used to log into accounts. A passcode is typically a short numeric PIN that unlocks a single device. A passkey is a modern, phishing-resistant credential stored on your device and unlocked by biometrics or the device lock — there's no shared secret to remember, type, or leak. Passkeys are the direction of travel: easier and safer than passwords because there's nothing to phish or reuse.
