Security within video chat applications is a hot topic at the moment. As remote working and virtual events become more prolific, the need for security will increase.

Within the Agora Platform, one layer of security comes in the form of token authentication. A token, for those of you that don’t know, is a dynamic key that is generated using a set of given inputs. Agora’s Platform uses tokens to authenticate users.

Agora offers token security for both its RTC and RTM SDKs. This guide will explain how to build a simple microservice using NodeJS and Express to generate an Agora RTC token. The example can easily be adapted to include an RTM token as it follows a similar pattern.

npm install express
npm install agora-access-token
