for you to ask for some thing like that would be illegal to do so when a member register at any community they would have to have privacy to there password by you seeing there password that would get you in lots of trouble for any member that would give you that request should be a shame to help you with that
i know i would not like any community that has the ability to see my password!!!let say they use there password from there email you would try to use that to hack there account so know i would not help you an anyway to do so thats my opinion !!! this is not a community for asking such request do it your self on your server sorry to be so blunt about it thank you
