Recover PDF Password is, as its name says, a program that helps you restore the lost access passwords for your PDF files. When encrypting multiple PDF files with different passwords, there's a good chance you might forget some of them - this is where this program proves to be of great use.
Unlike some applications from the same category, this personal security tool provides you with various search settings and can look for passwords that include lowercase characters, numbers, entire words, and much more. After you configured the search options according to your needs, select the password type (owner or user), and wait for the program to get the job done.
An important disadvantage of using this application is that it might take a while to offer you the results you require. For instance, when I tried to look for a lost password and the search began, the program displayed that I have to wait one day for the scan to complete.
Nevertheless, it's quite understandable to wait a while for this type of search to finish. And since the results are accurate, my belief is that this program is worth a try.
