The Name, and Team you use when you finish a Work Unit follows that WU forever.
You can change Names and teams as often as you like, and new WUs folded with those names will have those names forever as well.
If there was a way to make any changes, low lifes would steal your points and none of the rest of us would have any. If there is NO way to make the change, they cannot misuse that way.

At one time there was a search option to look for all points returned by a single passkey. That option went away during the move of the stats database from a Stanford server to the current location. A request was put in to restore that lookup, so it may return at some point in the future.
Using this link: https://apps.foldingathome.org/bonus I can search using just the passkey and it will show how many WUs were returned with that passkey.
