This is a summary of the key points about Daily's meeting tokens, which are used in the social gaming series Code of Daily: Modern Wordfare. Meeting tokens are JSON Web Tokens (JWTs) that contain user options and permissions for daily calls, and can be obtained from Daily's REST API or self-signed using an API key. The tokens are used to grant access to privileged resources or operations when joining a video call, and should be handled with care to avoid malicious use. Meeting tokens can be stored persistently on the client-side, but this requires careful consideration of security risks such as Cross-Site Scripting Attacks (XSS) and Cross-Site Request Forgery (CSRF). To validate meeting tokens, developers can use Daily's REST API or check their own signatures using a library like jsonwebtoken. The token payload contains claims such as expiry time, room name, and is_owner, which should be checked before validating the signature or making an HTTP request to Daily's validation endpoint.
