It would be very useful to be able to view a previously saved password for an item.
A few times times I have gone to change a password, logged into the relevant portal, generated a new password in the database (committed it) copied the new password into the portal only for it as a security measure to ask for the old/current password - which I know longer know!
Secondly, for sites/apps I am less concerned about security I sometimes use complex but memorable passwords to make regular logging in and out easier. it would be useful to be able to review older passwords to ensure that I don't reuse the same password again when changing it.
Thank you for the feature request. This is actually something we have planned for the near future!
