i keep getting a different password in my login,i cant get it to change,each time i try it reverts back to some 14 digit password that i dont know, so i am unable to login

The sniper does not show your password anywhere. You are probably confused with something else.

If you can't login to the sniper, please reset your sniper's password at https://www.myibidder.com/login/reset
Also, make sure you link your eBay account when you login to the sniper at https://www.myibidder.com/main/ebay

Once reset and linked, you can login to the sniper Windows app using the password you just set.
