If you don't want to use sandboxie, you can make a .reg file for each of your accounts (with some registry info related to your username and password) that you have to run each time you want to change the saved account information... but this requires to explore a bit the registry... i will make a guide for this in a bit (after testing that it works lol) ... the only issue is that you will need to have these .reg files floating around in a folder or somewhere... isn't much different than using the program anyways, but since i don't like to use such programs is good for me
