Curious about certificate

Hey, can someone tell me how does your certificate look? Does it have your name on it? Does it show your profile name or you can add the one you want? I wanted to add my name on certificate but I didn't know if there will be option for that so. Edit: I've seen some profiles recently and their certificates too. It looks like you can copy or save their certificate, is that true? And wouldn't it be easy for someone to just change name in anyone's certificate or fake it? That way it won't have much value tho.
