The Daily platform prioritizes security in its video chat APIs, utilizing WebRTC standards and encryption to protect user communications. To further enhance call security, users can implement additional measures such as adding safeguards to public room links, creating private rooms with tokens, and setting advanced host permissions. These features include generating unique, single-use room URLs, creating meeting tokens that control who can access a room and how they can participate, and setting properties on tokens like timestamps or time limits. By utilizing these security features, users can minimize the risk of unwanted guests joining their calls and ensure a secure video chat experience.
