I am using WSO2 IS 6.0. Is there a minimum client ID length required to set a client ID in OAuth/OpenID Connect Configuration? If there is any default length, how do I change it?
Thanks
There is no defined minimum length for client ID. When you are creating the application through REST API you can define the client ID (even if you input a single character as the client id, it will be considered). So, if the application developer/admin defines the client id be mindful to add an unguessable id.
If the client id is empty, a random id will be generated by the server. Refer to the code base. That generated client ID has a length of 28 characters. There is no config to change the default length for the generated client id.
