Is my password safe?

Well, it's true that someone may get confused for the "Trainer name" in the form fill overlay. This is a typical one:

I logged on to webmail and accepted Sxipper to remember my password. When I log off, Sxipper displays normally the gray clickable logon box.

However, right after "auto submit" checkbox there is a text which shows: "trainer: aStranger" without quotes. It's not my trainer name and I have not ever heard about that name. When I click the name, browser goes to aStranger.sxipper.com. It gives me a profile page. When I click "My Profile" on that page, browser goes to myself.sxipper.com, and "myself" is my first name. On other websites the gray box shows my login account, but doesn't show any trainer name.

I am the only user of this computer. Has Sxipper submitted my password to user "aStranger" or what happened?

Some basic concept of "Training", "Trainer Name" can be found in Sxipper FAQ. The relationship between the trainer and you is that the trainer provides a "map" (which information should be put into the form fields) for the form and you use the map that provided by the trainer.

See, the trainers share something with you but you don't reveal anything to anybody, including Sxipper server. In another word, YOUR passwords will stay in YOUR computer and be sent to the right website that YOU choose.

So, the answer is "Yes, your passwords are safe.". :)

And for those forms without a trainer name on it, it's trained by anonymouse user.
