Facebook asking me about my passport information?

[Maram Youssef]

I had a problem with logging in so when i wanted to contact them, they asked me to scan my passport or Id with my full name and birth date

so i captured my passport with my Iphone and i hided everything except my picture and my birthday and the place i was born and my length that was all which was shown,and even y picture isnt clear bec it was captured correctly but it was still shown
they sadly didnt inform me with anything useful to return my facebook account but i did something to be able to log in again
i just wanna know if that will cause me any problem? i have been afraid since i sent them the picture but i still feel sad because i hided all the important stuff and that i didnt scan it it was just an iphone picture and wasnt captured correctly
please tell me if they could do anything harmful to me with the information which was shown in the picture
sorry mistake ( it wasn't captured correctly but still shown* )
