Make Phishing Useless: ClassLink Passkeys Stop Attacks at Sign-In

Your team is drowning in password resets. Phishing keeps biting. MFA breaks when phones aren’t allowed. Enough.

Passkeys are now available in ClassLink. They’re the first step toward a passwordless future, delivering multi-factor security in a single step.

The Pain

  • Passwords get shared, reused, and stolen
  • Authenticator apps and SMS codes slow classrooms
  • Phone restrictions make MFA impractical
  • Resets explode during testing and back-to-school

The Fix

Passkeys. A cryptographic key pair on a user’s device, protected by Face ID, Touch ID, Windows Hello, or a device PIN. In one action, signing in with a passkey verifies two factors:

  • Something you have: the registered device
  • Something you are or know: biometric or PIN

That’s MFA in one step. Simple for users, strong for security.

Why K–20 Should Care

Goodbye Passwords, Hello Passkeys. Secure, Phoneless MFA for K–20.

  • Much harder to attack. No password to phish or reuse. Far less exposure to credential stuffing, brute-force, and dictionary attacks
  • Phoneless MFA. Works in phone-free classrooms and with younger students
  • Faster access. Approve with face, fingerprint, or PIN and get learning started
  • Reduced support load. Fewer password resets and less support tickets

How It Works in ClassLink

  1. Enable passkeys in your environment
  2. Users register a passkey on a trusted device
  3. At sign-in, the device signs a one-time challenge locally
  4. ClassLink verifies and grants access

No shared secrets. No codes. No typing.
