KeePass is a free password manager that's available for Windows, with unofficial ports for other operating systems.
Pro Allows storage of attachments such as pictures, documents and all kinds of files in general
Appending attachments to individual credential entries allows things like scanning important documents (for instance a scanned document containing the login information for your internet connection), appending them to the corresponding credential entry and afterwards destroying the original paper copy.
Pro Customizable password records
Users may define any extra fields (eg. "Surname", "Credit Card No", "Start Date", "Expiry Date" and "Security No") and their values may then be easily copy-and-pasted when required. This is a great feature not found in a lot of password-managers: they leave you to consign such additional information to the "Notes" section.
Pro Built-in history that tracks changes to individual credential entries
With the built-in history you can lookup previous passwords, track changes in general and if necessary recover those. In essence you are looking at a built-in Version Control System (VCS) which operates on single entries. Browsing the history of specific entries also displays associated metadata like the date of a change.
Pro Offers multiple sync options
Since the database is stored locally it can be synced across devices using a cloud storage service like Dropbox, Google Drive or via a file sync tool like BitTorrent Sync. KeePass v2 also provides a powerful built-in synchronization mechanism that allows setting appropriate level of sync, kind of sync, and choosing between a number of sync sources (Dropbox, Drive, etc).
