AccessToken lifetime from web app

I Register a Web Application and Authenticate a Web Application, AccessToken's Lifetime? Thank you.

protected void signInButton_Click(object sender, EventArgs e)
    {
        //Create a query string
        //Create a sign-in NameValueCollection for query string
        var @params = new NameValueCollection
        {
            //Azure AD will return an authorization code.
            //See the Redirect class to see how "code" is used to AcquireTokenByAuthorizationCode
            {"response_type", "code"},

            //Client ID is used by the application to identify themselves to the users that they are requesting permissions from.
            //You get the client id when you register your Azure app.
            {"client_id", Properties.Settings.Default.ClientID},

            //Resource uri to the Power BI resource to be authorized
            {"resource", "https://analysis.windows.net/powerbi/api"},

            //After user authenticates, Azure AD will redirect back to the web app
            {"redirect_uri", "http://localhost:13526/Redirect"}
        };

        //Create sign-in query string
        var queryString = HttpUtility.ParseQueryString(string.Empty);
        queryString.Add(@params);

        //Redirect authority
        //Authority Uri is an Azure resource that takes a client id to get an Access token
        string authorityUri = "https://login.windows.net/common/oauth2/authorize/";
        Response.Redirect(String.Format("{0}?{1}", authorityUri, queryString));       
    }

public partial class Redirect : System.Web.UI.Page
{
  protected void Page_Load(object sender, EventArgs e)
  {
      //Redirect uri must match the redirect_uri used when requesting Authorization code.
      string redirectUri = "http://localhost:13526/Redirect";
      string authorityUri = "https://login.windows.net/common/oauth2/authorize/";

      // Get the auth code
      string code = Request.Params.GetValues(0)[0];

      // Get auth token from auth code       
      TokenCache TC = new TokenCache();

      AuthenticationContext AC = new AuthenticationContext(authorityUri, TC);
      ClientCredential cc = new ClientCredential
          (Properties.Settings.Default.ClientID,
          Properties.Settings.Default.ClientSecret);

      AuthenticationResult AR = AC.AcquireTokenByAuthorizationCode(code, new Uri(redirectUri), cc);

      //Set Session "authResult" index string to the AuthenticationResult
      Session["authResult"] = AR;

      //Redirect back to Default.aspx
      Response.Redirect("/Default.aspx");
  }
}

public partial class _Default : Page
{
  public AuthenticationResult authResult { get; set; }
  string baseUri = "https://api.powerbi.com/beta/myorg/";

  protected void Page_Load(object sender, EventArgs e)
  {

      //Test for AuthenticationResult
      if (Session["authResult"] != null)
      {
          //Get the authentication result from the session
          authResult = (AuthenticationResult)Session["authResult"];

          //Show Power BI Panel
          signInStatus.Visible = true;

          //Set user and token from authentication result
          userLabel.Text = authResult.UserInfo.DisplayableId;
          accessTokenTextbox.Text = authResult.AccessToken;
      }
  }

  ...
}

@xuandungpy

By default, the token expires in one hour. You can find the expire time("exp" field) after decoding the token.

Check more Configurable token lifetimes in #AzureAD.
