[User Authentication Integration for Website & App](https://freelancer.com/projects/web-development/user-authentication-integration-for.html) I currently have a website that does not require user authentication or sign-in. I have also developed an Android app that similarly does not support user sign-in or authentication. Before proceeding with the Android app deployment to the Google Play Store, I am considering implementing a sign-in system so that users can create accounts and access personalized features across both the website and the mobile app. **Skills required** __Android, Android App Development, API Development, Java, Mobile App Development, PHP, Web Application, Web Development__ 💰**8USD/Hr - 15USD/Hr** 👤[Bidhanchandradeb](https://freelancer.com/u/Bidhanchandradeb.html) from...
