oauth tokens don't work across machines - create more specific tokens?

[cwittern]

Here is the scenario:
Access github account from one machine, through oauth, a token gets created and cached on this machine.
On another machine, access the same account. Since a token exists, none gets generated, but there is no token locally either, so the access fails.
Github does not allow (anymore?) retrieval of tokens after they are created, so the token needs to be account & machine specific (I think, but I do not actually understand the magic behind all this, so thinks might work quite differently), and, as has been suggested, it would be cool to be able to invalidate them and get new ones.

I saw this too.
