Imitation sites copy the look of a real one exactly. The address is the one thing they cannot copy.
Phishing is the practice of deceiving people into revealing sensitive information, often through a counterfeit website reached by a link in a message. See Wikipedia's article on phishing. The page design, logo and wording are lifted from the original, so appearance tells you nothing.
The part that matters is the registered domain, immediately before the first single slash. In secure.example.com.login-check.net/account the site is login-check.net. Everything to the left is decoration chosen by the attacker.
A padlock shows that the connection is encrypted. It says nothing about who is at the other end. Imitation sites have padlocks too.
Change the password immediately from the genuine site, sign out other sessions, and tell your bank if payment details were involved.
