Q: What is a "key file"? A: A key file is the technical term given to a computer file that is used as an alternative to providing a password. In other words, instead of entering a password to access your password database, the program checks the authenticity of a predetermined file of your choosing. The key file could be as simple as a text file that you create, or it could be a file that was created by someone else, such as a binary file from an application, a pdf file, etc. One benefit of using a key file instead of using a password is that you do not have to remember a password. All you need to do is point the FPM2 application to the location of the key file. The key file could reside on a hard drive, a USB flash drive, a CD-ROM, etc. Q: What happens if I forget the master password or if I lose the key file? A: The only way to access the contents of a FPM2 database is by providing the proper authentication (either the master password, or the key file). There is no way to circumvent this security feature. This is actually a good thing. The application would be less secure if there was a "back door" coded into the software. Q: Why does FPM2 not remember my key file location? A: For security reasons, FPM2 does not save the location of a previously used key file. This provides one more layer of security to prevent an intruder from knowing where to look to find the key file, or even knowing that a key file is being used instead of a password.
