MyBB Community Forums

Hello, I'm making a connection between an external system that uses NodeJS with the user data that are registered in the forum, the clear difference is that in one place we use PHP and in another we use Javascript and I was wondering what was the most efficient way to continue with the login system. I can get the email and password but... How do I tell the forum to log me in for that specific session? I'm sorry if my English is not very good.
