There is no point in having security software that has a back door or can otherwise be hacked for access. APO is security software that is effective at keeping your information secure. If you forget your login details, we cannot help you.
As you re-build your password file, we would suggest you take the following precautions:
1. Keep your Username and Password written down in a secure place. Perhaps with your will. If you get hit by the proverbial bus, there will likely be loved ones who will need access to some of your things. At the least, they will need to access certain sites in order to transfer your music/movie/book collection, and who knows what else.
2. If you have created multiple APO files, be sure to keep the username and password for those extra files in your Personal file. Not being able to remember multiple login credentials is why you got APO in the first place.
