I want to login and sign up the user from android app, i already know that should install some plugins on the word-press website.
I tried to use open source project but it didn't work Here's login and signup using wp-rest api
I need guidance on the requests i will send from client side and is there app secret or password that i need to generate to authenticate the app.
Try to use this plugin, and follow the instruction in the page: https://wordpress.org/plugins/jwt-authentication-for-wp-rest-api/
