A passkey is an authentication or access code used to verify a user’s identity or grant access to a system, application, or service. They ensure that only authorized users can access a system or resource.

Passkeys are typically comprised of a combination of characters, such as letters, numbers, and symbols, and vary in complexity, ranging from simple passwords to lengthy and highly complex combinations. Strong passkeys are more resistant to brute-force attacks.

How are Passkeys Used?

  • Multi-Factor Authentication: Passkeys are often used as one component of multi-factor authentication (MFA), combining something the user knows (the passkey) with something the user has (e.g., a mobile device).
  • Passkey Policies: Organizations often establish passkey policies that define criteria for passkey complexity, length, and expiration to enhance security.


Passkeys represent a fundamental aspect of modern cybersecurity, serving as the keys that unlock the digital gates guarding our most valuable assets, information, and resources.

These digital keys, often in the form of passwords or access codes, are the linchpin of user authentication and access control in our digital world.
