I’m an application developer and try to make an application for a WordPress site. I need to use rest API to log in and signup users to our WordPress site. I found create-a-user API on WordPress official site. But not found anything for log-in API. Our WordPress site creator told me that to log in and signup users on the site, they installed userpro plugin on WordPress. So, How can I log in and signup users with the rest API in my application? There is no documentation for the userpro API.
