autoincrement in domain data model

Hi, I'm fairly, exploring the amazing capabilities of Mendix. I cannot figure out how to set a "column" (attribute of my entity) to autoincrement. I have created Users entity under domain model as I want to create data model for user data. My goal is obviously to increment User_ID for each new account created. I saw in the System administrator, Password are stored under different entity, not sure why but I guess this would be offtopic. I will appreciate any advice!

Not completely sure what you mean with autoincrement, but if it is a number that you want to store in the column attribute make sure it is set to Autonumber and this will automatically increment the number every time a new record is created in the entity.
