data flow

Users (id) -> Apps (id) -> Devices (id) -> Sessions (id) -> Messages

android client

client needs to generate a protobuf from loggy/loggy.proto

Web

• Login - Access Token
• Rest API - Using Gin
• db as users

GRPC - Web

• Access Token and User ID in the metadata

GRPC Android

• Client ID to validate (constant)
• Associate client id with app id (web integration)

Server

• Access Token review

• Secret to generate access token is hard coded

• Client ID generation (short string)

• Should be able the user id
