I use my password manager sharing feature as sending document by email is less secure, document is retained by all email and cache server, while PM (password manager) keep the document e2e encrypted with an expiration date. Other thought, having important document available easily on a day to day in the PM might lower the overall security of those document - I do handle this by having 2 PM accounts. While the emergency contact might be activated to get access to this account, will the new owner have access to all documents, even those >100 items and >10gb of a previously paid account that failed to renew (access within reasonable time frame of 1-2 years) ?
