Get Email

I've been searching but haven't found an option to obtain the user's email, neither through Google nor Facebook. This would be very useful for registering the user in the database in addition to using the ID, because if there's a problem with the API, until it's resolved it would be possible to access the account using the email and password, and to create a password it would be necessary to send some confirmation code to the user's email, as well as other things like notifying about an event by email and ...

What users? What api? What database?

Unless you make a game that requires a login and requires their email in the registering process you won’t get emails of people.

Considering your post isn’t spam you haven’t written a complete thought.

Like many websites nowadays, I'd like something similar: login with email and password, and login with just one click, in this case via Google or Facebook. However, if the user chooses to log in via Google or Facebook, I'd like to have the option to retrieve the user's email address as well. This would be useful in case of an error or API update, and while the system is down, the user would have the option to use their email to access their account.

Most authentication services don't provide an email address for privacy reasons. You would probably have to ask the user to enter their email address separately.

I understand, but taking Facebook as an example, it has the option to ask the user's email in addition to their public data, and then the user decides whether to accept or not. However, when they accept, there would have to be code to retrieve the email, and I even tried creating this code with JavaScript and it worked, but when exported with minification it doesn't work. That's why I suggested a code within the plugin to retrieve the user's email, not only on Facebook but also a Google plugin would be good, not the Google Play Games plugin, but the Google plugin itself, which many websites use as an alternative for registration and login.
