Not using current code and I am not going to change that. I would not risk storing passwords. Security on my servers is very strong but you never know. I would not want to compensate people if their accounts are hacked.
I think I have to keep my site up for a long time to eventually build the trust but it will eventually happen
No one will get your password. Even I can not see it. It is in the RAM on the server. If you too paranoid change the password right after your order is executed. Orders will take less than a minute to execute if they match
Dishonesty gets you nowhere. It is one thing to tell people they should trust you with their Paypal password (a dubious business model) it is another to blatantly lie.
If you have admin access on your server then you have the ability to see/record/sell the passwords. The fact that you "won't" doesn't mean you "can't".
