I share passwords with my coworkers (for resources that don’t support teams+sub-users) not by using any password manager, but rather by just keeping the descriptions+usernames+passwords in a Google Sheet.

We use GSuite, but that isn’t really relevant other than for controlling default ACLs to the document; you can just make a private Sheet and then share it by email to whoever you like.

Google Sheets works okay (for this use-case) pretty much everywhere you need it, including on mobile. Doesn’t auto-fill anything, of course, but since the point is sharing the password, not restricting the ACLs of the password in any enterprise sense (i.e. so people that could use a password before can then lose access to it), it’s fine to allow people to just cache the password into iCloud Keychain and/or Chrome Sync. So it’s not as much of a speed bump as you’d think.
