Question about whether somebody can use their account in a facebook app while oculus is installed linked to a Quest 2 with a separate facebook account.

OK we have an android phone with the Oculus app installed logged in with a facebook account (facebook account A) and linked to a Quest 2 headset.

Somebody else (not me) with facebook dropped their phone in a puddle in the rain last night. Can they log into the facebook app (Facebook account B) while Oculus is installed on the same device logged into (Facebook account a) and currently connected to a Quest 2?

​

Does that make sense?
