Yeah, that's what it shows. You can change your username: https://forum.unity.com/threads/nothing-special.619684/#post-4328515

 

It's a very bizarre side effect of the way they implemented logging in with Facebook and Google.

 

I've always thought that logging in from other places like those two was a very bad idea. I prefer creating a real account instead.

 

Plus, it seems to infringe even with their own branding guidelines.

Where "handle" probably stands for forum names too.

 

As the usernames are provided by Unity, this is actually explicitly not the case.
