# User Management

At the core of many apps, there is a notion of user account management that lets users access their information in a secure manner. A specialized user class called `ParseUser` is available to automatically handles these kind of functionalities.

`ParseUser` is a subclass of the `ParseObject`, and has all the same features. All the methods that are on `ParseObject` also exist in `ParseUser`. The difference is that `ParseUser` has some special additions specific to user accounts.

## Signing Up

```java
import com.parse.ParseException;
import com.parse.ParseUser;
import com.parse.SignUpCallback;

public void signUpUser(String username, String password, String email)
{
    ParseUser user = new ParseUser();
    
    user.setUsername(username);
    user.setPassword(password);
    user.setEmail(email);
    
    // other fields can be set just like with ParseObject
    user.put("phone", "650-253-0000");

    user.signUpInBackground(new SignUpCallback() 
    {
      public void done(ParseException e) 
      {
        if (e == null) 
        {
          // Hooray! Let them use the app now.
        } 
        else
        {
          // Sign up didn't succeed. Look at the ParseException
          // to figure out what went wrong
        }
      }
  });
  
}
```

{% endtab %}

{% tab title="Swift" %}

```swift
import Parse
​
class testVC: UIViewController
{
    func SignUpUser(email:String, pwd:String)
    {
        let user = PFUser.init()
        user.username = "demo@symbyoz.io"
        user.email = "demo@symbyoz.io"
        user.password = "demo"
        
        user.signUpInBackground
        {
            (isConnect, error) in
            
            if let error = error
