Login only with email? (required this to implement social login on mobile apps)

[gtu-myowin]

Hi, I came here from https://github.com/Tmeister/wp-api-jwt-auth and I have installed your plugin https://wordpress.org/plugins/simple-jwt-login/

I am trying to implement social logins (Facebook, Google, Twitter, LinkedIn & Apple) for my Flutter mobile apps backed by WordPress. I wonder

1. if it is possible to login with email only and get JWT token with this plugin because I will get only name & email from social sites. Even if I have register user with random password, they will still use social login in future and email is the only reliable data I would get from social sites.
2. or since WordPress has the ability to get user by email & login without password, I can do that by registering a custom endpoint but how do I get or generate JWT token in this method for future authentication?

Thank you for your effort on the great plugin and supporting.
