Authentication

The NATS server provides various ways of authenticating clients:
​Token Authentication​
​Username/Password credentials​
​TLS Certificate​
​NKEY with Challenge​
​Decentralized JWT Authentication/Authorization​
Authentication deals with allowing a NATS client to connect to the server. Except for JWT authentication, authentication and authorization are configured in the authorization section of the configuration.
