When is user.email null?

Hello. In what scenarios will email be null. When a user logs in, I would expect that would not be null. I would need to manage user quota/usage on the backend if I go with a subscription based format.

I don't think user.email is ever null since an email address is required for a free trial.

However, using email address as a unique identifier may be difficult since a user has the ability to change their email address.

The API key can change as well.

So, we have to generate our own internal ID to track a specific user then is what it sounds like. alright, thanks!
