How do you manually expire a token with Meteor?

Okay so I want to create a system where a user can be invited. This is trivial with Accounts.sendEnrollmentEmail. But the catch is that I also want to allow for an unaccepted invite to be expired manually.

That is, when a user follows the link to their password reset page, it will know that their invitation is canceled, and not allow them to reset their password

Is this possible with meteor?
