We are using version 2.0 of tyk.io, and we wanted to know if there is a way to customize the tyk.io dashboard ui to use a custom authentication method such as Oauth2?
To clarify - Do you mean using OAuth for controlling access to the tyk dashboard itself?
If so, take a look at Tyk Identity Broker - that should do the trick. https://tyk.io/tyk-documentation/concepts/tyk-components-2/identity-broker/
