When a user signs on for the first time, I want to force the user to change the password they are given.

I am able to create the user with a password.

And then activate the user, with an email (which is what I want). (See below)

But, I can not figure out a way, using the OKTA SDK for dotNote, to then expire the password to force the user to change it.

I did find information related to nextLogin = changePassword. But, I can’t seem to figure out how to use it with the SDK. (See below.)

Within the SDK there is a UserNextLogin class but I don’t know if that as anything to do with it.

Any help would be appreciated.

```
        var oktaUser = await client.Users.CreateUserAsync(new CreateUserWithPasswordOptions
        {
            // User profile object
            Profile = new UserProfile
            {
                FirstName = "Anakin8",
                LastName = "Skywalker8",
                Email = "test@gmail.com",
                Login = "darth.vader12345678",
                
            },
            Password = "D1sturB1ng!",
            Activate = false,
        });

        await oktaUser.ActivateAsync(sendEmail: false);

        var userNestNextLogin = UserNextLogin.ChangePassword;
```

Hi @rcorkery

If you take a look at the [SDK source code](https://github.com/okta/okta-sdk-dotnet/blob/1849eb0d2b199d3e3fc2723bb4dc732c7b135352/src/Okta.Sdk/Generated/IUsersClient.Generated.cs#L37), you’ll see that you actually need to pass `nextLogin=changePassword` in as a query parameter to `CreateUserAsync` in order to prompt the user to change their password the next time they log in.
