I honestly don't care that much about privacy in regards of sharing a password, but i was looking for a solution to use in my agency so my clients feel safe and secure.
I was looking for something simple and found it with inprivy.
It is a super simpel dashboard that can be completely branded, even with a cname link so it's 100% a tool from my agency and it works.
Great, nothing fancy but that was exactly what i was looking for!

( To the developer - maybe you can provide me with a little guide on how to upload my own css document: i want to increase the size of the logo that's displayed on the site where someone can enter their secret and it's quite small)
