Password Sharing

Hello, I have an wonderful idea for a feature request I’d like to share… This would be the ability to share a password with a user or group that meets a specific set of criteria 1) The destination for username/password would be exact match as so cannot be pasted in any areas but which intended, 2) Shared user cannot edit or even see any information pertaining to said username/password share, they only have permission to use it where it was intended to be used, and 3) Sharing user can revoke rights of usage to any shared user/group at any time as they control all rights to said username/password… This would allow one to share confidential login or whatever encrypted data with another without actually divulging anything, it’s simply a permission to use it on your behalf
