How can I implement custom authentication in Xamarin.Forms?

To implement custom authentication in Xamarin.Forms, you can create a service that handles user login, token management, and session validation.

What libraries or packages do I need for this?

You might want to use libraries like Newtonsoft.Json for JSON handling and HttpClient for making API calls.

Can you provide a code example?

Sure! Here's a simple example:

public async Task<bool> Login(string username, string password) {
    var client = new HttpClient();
    var response = await client.PostAsync("https://yourapi.com/login", new StringContent(JsonConvert.SerializeObject(new { username, password }), Encoding.UTF8, "application/json"));
    return response.IsSuccessStatusCode;
}

How do I handle token expiration?

You can check the token's expiration time before making API calls and refresh it if necessary using a refresh token.
