How to log in icloud mail?

Hi all!

My mom's icloud is locked because of wrong password. My mother does not remember the password. I unlocked by sending icloud mail and do not know how to log in icloud mail?
I tried unlocking by answering a security question. Do not know why the wrong date of birth of my mother? Maybe while registering my mom's account I hit the wrong date of birth. Can you help me?
Thank you very much!
