How to login to server with user credentials without using speckle frontend

Hi Dimitrie,

We need programmatically login to be able to subscribe specific streams. If our server down and up we have to subscribe streams again. Since we do not have any Account to initialize speckle gql client at this point, we wanted to use admin credentials to do that.

I have a question regarding implementation of pre-registered apps. Is that something like speckle main app(frontend) or GQL explorer?
