Currently I'm using the anonymous auth method, but since I've noticed that this ID just changes after a while, I want to use my own ID for authenfication, i store a user_id (on my MySql database) based on a hash value that on the same device is ever the same, this id i want to use in Firebase. I dont find a tutorial here to implement it, maybe a user have experience with it.
