An Application Programming Interface (API) token is a digital credential used to authenticate a client—whether it's an application, a service, or a user—to a server. It acts as a temporary key, proving the request comes from an authorized source without requiring the client to send their full login credentials repeatedly. The creation of this token is a crucial security process that must prioritize randomness, uniqueness, and verification.

How Does a System Generate an API Token?

When you log into an online account and it asks for a 6-digit code from an authenticator app—like Google Authenticator, Microsoft Authenticator, or Authy—you’re using something called Time-based One-Time Passwords (TOTP).
