This hasn’t been true for 8+ years.

Everyone here is slightly wrong.

Meta does require you to have a Facebook account. The expectation is that it is your personal fb that you use regularly. However, it doesn’t need to be. You can create a new fb account with a new gmail account and that’s fine. That’s what I did and some others do as well.

That said, 90%+ of employees end up using their real personal account because the language they use makes it seem like you couldn’t do what I described.

No they do not lol.
