How to compare passwords with duplicate password



On Steam, the gaming client, I have this habit of creating multiple "smurf" accounts.


I have a randomly-generated, unique password, and I decided to use the same password for all of my multiple accounts. On my fifth account or so, Steam has started preventing me from using the same password again.


How does Steam know whether a password has been used before without compromising my security?
