Basic Admin: Password Management

Been exploring password management solutions for my company and thought to research whether management of the Edge browser via Azure could stand in for a dedicated vault. Are organization users' credentials accessible to admins beyond the portal reset procedure? Do other tools or integrations exist to share common credentials across select subsets of users? Would Seamless SSO be suitable for these purposes? Responses elsewhere imply there might be legal implications to consider.

I'm sure most would tell me to just use a dedicated vault/manager, but I'm really trying to avoid introducing additional apps or steps to our team.
