False.  Every device has A fingerprint.  There is absolutely nothing 'individual' or 'unique' about it.  https://en.wikipedia.org/wiki/Canvas_fingerprinting  Fingerprinting is for marketing.  Not security, and should never be considered when addressing security concerns either.  For example,  it's ok to pass out a flier to a group of people with similar likes/dislikes,  but its not cool to toss a grenade into that same group of mixed people with similar likes/dislikes simply because you know somewhere in there are some bad guys.  And the claim that " exactly the same techniques that every other online casino uses" for security is just utterly retarded.  No casino in their right mind would use canvasing for security.  Ever.  For advertising?  Absolutely.  For security?  Not a snowballs chance in hell unless they were completely stupid.  I'm starting to suspect you dont even know what "Canvas" actually means let alone fingerprinting of the canvas element.  But thats not surprising since you're not an IT security person.  However it doesnt excuse you from attempting to make it sound like you know what you're talking about.  The correct reply should be "What is canvas fingerprinting,  I dont think we use that".
