Job ID: 37726676

Budget: $10 – $30 USD

Frontend: React Native Expo Web
Backend: .NET Core 6 Web API

Both frontend and backend are already 80% coded.
This is more like a bug fixing, not a new feature implementation.

Task:
1. Finish JWT authentication and authorization, so that when user logged in with email and password, he does not need to logged in with password within 24 hours.【10 USD】

2. Prevent different people sharing one account. At any time, only one user can be logged in with an account.【10 USD】

You have to work remotely on my computer via AnyDesk.
No other options. Thanks in advance.
