I am new to Auth0, I have an app that requires a unique user Id for a user to carry out certain tasks.
I understand that I can create custom claims for the user id. My question is, can I use the ‘sub’ claim as an ID for the user? Is it a bad idea to use the sub claim within the app, store it in the database and use it for that purpose?
Welcome to the Community!
You can definitely use sub as your user id.
Hope this helps!
