does facebook support otp 2fa, or just sms

Facebook supports OTP 2FA. Use it.

Does it still require you to have the Facebook app installed, or can you use a 3rd party tool like Authy now?

Any Authy or Google Authenticator -like app works. I personally use Authy.

You can use any 3rd party tools.
