SHaring a password securely with a team member VA

Hi, 

I have recently joined a business community, and they mentioned that they share a one off password generated in their password manager each time for their VA - I am considering getting a VA. What is the best way to manage a password when bringing on a team. I am one of your original customers in 1 password 5 so not on a plan, I paid one off for the app. It's been great!
