Summary

OAuth 2.0 is an open standard for token-based authorization used on the internet, allowing clients to request access to resource servers without revealing user identity. Access tokens, which expire periodically, are essential for making requests, while offline refresh tokens can extend access without user intervention by refreshing the access token when it expires. For online access, apps may require user reauthentication relying solely on the access token. JSON Web Tokens (JWTs) are used for short-lived authentication in Cloud IoT, composed of a header, payload, and signature, all encoded in Base64 URL format. Various strategies exist to manage token expiration, such as monitoring HTTP responses for 401 errors, checking token expiration dates proactively, and combining these methods to handle token expiry during requests.
