We use Delinea Secret Server (formerly known as Thycotic Secret Server) for several years to store all credentials. No affiliate. I am user of the system and not an admin, so can't comment on the admin part, but for an end user it works very well. We are consultancy and we use it to store all credentials to our clients systems. You access through a web interface. Had made my life easy when it comes to managment of my credentials.
