Firestore What should I set the user's document id to?

I noticed that when creating a new document(new user) in Cloud Firestore, Firestore will randomly assign an id. Should I instead set this Document to the manually generated User UID? If not, how do I reference the randomly generated Firestore Document Id when updating the fields in said document?

There is no single correct answer here, but most apps use the UID of the user as the document ID for that user's profile in a users collection.

One reason for this is that it allows a direct lookup of the user's profile document based on their UID, which is typically the most common way of identifying a user in an app.

Using the UID as the document ID also ensures that you can only have a single profile document per UID, which is a common requirement.
