-// Currently, the only supported use-case is obtaining Android applications
-// affiliated with the web site containing the observed form. This is achieved

-// More specifically, this class prefetches affiliation information on start-up
-// for all Android applications that the PasswordStore has credentials stored
-// for. Then, the actual GetLogins() can be restricted to the cache, so that
-// realms of the observed web forms will never be looked up against the
