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.
