The number of passwords we modern users must remember isn't getting any smaller. From social media to shopping sites, Web-based mail to online banking, site after site demands a username and password. Using the same password for all of them is a really, really bad idea, since a single data breach would totally wipe out your online privacy. But remembering dozens and dozens of passwords (over 200 in my case) just isn't feasible.
A password manager is software that helps a user organize passwords and PIN codes. The software typically has a local database or a file that holds the encrypted password data for secure logon onto computers, networks, web sites and application data files. Many password managers also work as a form filler, thus they fill the user and password data automatically into forms. Secured by a single ultra-strong password, something you can remember but nobody else would guess, they store your passwords and automatically recall them as needed. The best password managers also function as automated Web form fillers.
Password manager software can also be used as a defense against phishing and pharming. Unlike human beings, a password manager program can also incorporate an automated login script that first compares the current site's URL to the stored site's URL. If the two don't match then the password manager does not automatically fill in the login fields. This is intended as a safeguard against visual imitations and look-alike websites. With this built-in advantage, the use of a password manager is beneficial even if the user only has a few passwords to remember. While not all password managers can automatically handle the more complex login procedures imposed by many banking websites, many of the newer password managers handle complex passwords, multi-page fill-ins, and multi-factor authentication prior. So, password manager software organizes your passwords very easily without any hassle.
