When manage many passwords, database becomes contain many old passwords, that not used long time, but interfere in filter results. Also when stored several logins/passwords for same page, will be good to see which is last used, and which is not used long time.
So users often want to clean-up garbage password like this.
For detect those passwords, will be good to store last access (open, use) time for all items, and ability to sort/filter records by access time. What do you think about this idea?
