Hello, Friend of your Facebook account is a temporary lock then try the bellow process to open your Facebook account.
After putting user name or mail id & password then you got this type of page that means your Facebook is a violation of any Facebook rules. you need to fix it step by step.
After you click the continue button then you got two options one is to Text a Security code to your phone and another is to identify photos of friends. We can check both options for knowledge. now chose to identify photos of friends.
Again Chose to identify via phone number this option is a little easy.
Click on continue and set a strong password
I also added a video tutorial for fixed the Facebook login issue.
