Q's new trip is a Secure Trip..
Whereas a regular trip is inserted to the name field with a password like
> Q #p@ssword
> which hashes out to Q !tRipCoDeQQ
A Secure tripcode is relegated to a salt that's stored on the website, meaning it cannot be brute forced from something like the tripcode explorer, or guessed upon on another imageboard like 4ch. It also means that the secure trip will not be the same on any other imageboard if entered correctly- so Q is in essence dedicated to 8chan.
It's inserted as such:
> Q ##s3cureP@ssword
> which hashes out to Q !!SeCuReTriP
