I'm sorry if this is not the place for it, i'm a newbie programmer. I just saw about the 'metadata' customization thing of supertokens. But i feel like storing user related info in my own db by binding the user id from supertokens to my db is a better way, and using supertokens only for auth. Is this how it usually goes? Is there any advantages of using userdata other than simplicity (like not having to use another db)?
