v6 of the FAH client comes with a new feature: the use of a passkey (http://folding.stanford.edu/English/FAQ-passkey). From the FAQ about the passkey, the following is said to be the purpose:
QuotePreviously we have not had unique identifiers in Folding@home (usernames for example can be shared by many people). One main benefit of passkeys is that if someone cheats, we will not need to zero out the points of everyone with that username -- only the offending party and those without passkeys. Perhaps more interestingly, we plan to shortly institute credit bonuses, which will be tied to passkeys. Finally, the existence of passkeys opens up future possibility of displaying your individual credit and other information, rather than just by username.
I just wonder if anyone has tried this, and if so it everything has been smooth or they have experienced any problems?
I haven't made the change myself but I have read a few articles by ppl that have. The swap is easy and even the beta-clients support it.
