Authentication Handler
Noun · Development
Definitions
A component that receives authentication-related requests and coordinates validation, token issuance, redirects, or session setup. Authentication handlers often sit at the boundary between transport logic and identity services, translating framework-specific request details into auth decisions.
In plain English: A component that processes login and authentication-related requests.
Example: "They split the authentication handler out of the monolithic middleware so different login methods could share the same token-issuance path."
