Can I share turbo tax 2023 product key with a family member if we have different turbo tax log in accounts?

In the past I have purchased Turbo Tax with a family member to share costs.  They have their own Turbo Tax user ID and password.  We plan on only using on 4 computers total.  With the new Product Key System  we want to conform it will work for us or do we need to purchase our own Product Key?  We only file 3 returns in total.
