My friend has been using her Facebook account very frequently via her Facebook app. Because the app was never signed out so she forgot her password and worse, she didn't even have any email addresses attached to her account. However, she does has access to her phone number which she told me that she used that phone number during the signup process.
How can she recover her account using her phone number? I tried to help her to recover her password but kept getting the same thing as in the attached photo.
