I imagine the parent's question was moreso "share any credential between any two accounts" (as a multi-to-multi relationship), rather than being limited to sharing any/all credentials between exactly two accounts, which is extremely limiting beyond a pair of spouses.
Of course, Bitwarden also has the "Families" paid version, which costs... $1/month for up to 5 users (that's $1/month flat for all 5 users, not $1 per user). $1/month for a whole family is beyond reasonable, and precisely why I love Bitwarden – it's great software with prices designed to support a single developer's open source software rather than the exorbitant prices required to support an entire company and their proprietary software.
They did state two accounts and not multiple, but I see what you're saying. It should be known, however, that you can share without paying. I also encourage people to pay -- it's cheap and the service is fantastic.
