Restrict permanent deletion to admins or family organisers only

Sounds solid - presumably in combination with an archive-only feature for non-admins?

As an admin, I've noticed that a member moved items to their private account and then permanently deleted them. Unfortunately, I cannot prevent this, so we need more control over family shared accounts.

Hello @Marghlani! 👋

Thank you for reaching out! If you're using 1Password Business then you can configure the Delete items permission for a vault: Manage permissions

With 1Password Families you can configure whether members of a shared vault have the ability to edit items in that vault (including deletion): Manage access

Would these options fit your needs? If they don't then I'd be interested in knowing more about your requirements here so that I can share with our product team.
