Additional claims missing in asp net core identity after 30 minutes


ASP.NET is a popular programming language used for building web applications. It provides a for developing dynamic websites, web services, and web applications. One of the key features of ASP.NET is its to handle user and authorization through the use of ASP.NET Identity.

Understanding ASP.NET Identity

ASP.NET Identity is a membership system that allows to manage user authentication and authorization in their web applications. It provides a set of APIs and components that handle user registration, login, password management, and role- access control.

When a user logs in to an ASP.NET application, ASP.NET Identity generates a security token that is stored in a cookie or a session. This token is used to authenticate the user for subsequent requests. By default, the token has an expiration time of 30 , after the user to reauthenticate.

Additional Claims Missing

In some cases, developers may encounter a situation where additional claims are missing in ASP.NET Core Identity after 30 minutes. Claims are key-value pairs that represent user attributes or properties. They can be used to store additional information about the user, such as their role, email address, or any custom data.

When a user logs in, ASP.NET Identity retrieves the claims associated with the user from the database and includes them in the security token. However, after 30 minutes, when the token expires, ASP.NET Identity only includes the basic claims required for authentication, such as the user's ID and username. Additional claims are not included by default.


To solve the issue of missing additional claims in ASP.NET Core Identity after 30 minutes, you can implement a custom solution that the security token and includes the additional claims.

One approach is to use the Refresh Token functionality provided by ASP.NET Identity. The Refresh Token allows you to generate a new security token without requiring the user to reauthenticate. You can extend the expiration time of the token and include the additional claims during the refresh process.

// Example code for refreshing the security token and including additional claims
public async Task RefreshToken()
    var user = await _userManager.GetUserAsync(User);
    var refreshToken = await _userManager.GetAuthenticationTokenAsync(user, "MyApp", "RefreshToken");

    // Refresh the security token
    var newToken = await _signInManager.RefreshSignInAsync(user);

    // Include additional claims
    var additionalClaims = new List
        new Claim("Role", "Admin"),
        new Claim("Email", "")

    // Update the security token with additional claims
    await _userManager.AddClaimsAsync(user, additionalClaims);

    // Return the new security token
    return Ok(newToken);

In the above example, we first retrieve the user and the refresh token associated with the user. We then refresh the security token using the RefreshSignInAsync method provided by ASP.NET Identity. After refreshing the token, we add the additional claims to the user using the AddClaimsAsync method.

By implementing this custom solution, you can that the additional claims are included in the security token even after 30 minutes. This allows you to access the additional claims throughout the user's session without requiring them to reauthenticate.


ASP.NET Identity is a powerful tool for managing user authentication and authorization in ASP.NET applications. By understanding how to handle additional claims and refreshing the security token, you can ensure that the necessary user attributes are available throughout the user's session.

Remember to always consider the security implications of including additional claims and ensure that sensitive information is properly protected.
