At VTEX, the customers are identified in the system through their emails. However, if they want to make any changes to the data entered during their first purchase, they must confirm the ownership of the email account in question. For this, some alternatives are offered, including Facebook.

To configure a Facebook registration, follow the instructions detailed in this article about the registration of Client Id and Client Secret for login with Facebook.

4. Click on the Save button.
5. To confirm that your login was successful, go to the front-end of your store and click on Login.
6. The configured login options will be shown. Click on the Facebook option and check if your store name is displayed.
