Serverless functions validate credentials, issue tokens, and log authentication events. Each login request is isolated, improving security and scalability. Systems can handle sudden login spikes without failure. Since functions don’t persist, attack windows are reduced. This makes serverless ideal for modern identity workflows.
Authentication systems become more scalable and resilient. User trust improves.
This supports secure growth of digital platforms and services.
Serverless functions often power authentication and authorization flows.
