@mtas-test thanks for filing the issue! It looks like it probably would have been a good idea to make a required v8 Checkbox label style, but unfortunately adding one now would be a breaking change for v8. I have made a Codepen to demonstrate how to make your own custom required "*" style that matches the one on Textfield: https://codepen.io/smhigley/pen/JjgZWXa?editors=1010

I don't really know what you mean by enforcing required behavior -- we don't provide out-of-the-box form validation in Fluent, that is generally left up to product teams. Setting the required attribute on the Fluent Checkbox does actually set the native required HTML attribute on the underlying <input type="checkbox">, which will trigger native browser validation on the checkbox on form submit, if you're not turning that off. Even if native validation is not used, setting required will provide the required semantics to show that the checkbox is required to e.g. screen reader users.

Hope that helps! Feel free to reach out with any other questions.
