Hello! @admin
Welcome to the LastPass Community.
Using your LastPass account you have two options to share passwords, single sharing, and shared folders.
Using both options for the shared passwords should update automatically without re-sharing each time.
The single sharing passwords is available for all our tiers, free, premium, families.
Shared folders are available just for LastPass families and business.
Please let me know if you need additional help.
Greetings!
