It's possible that the website uses elements known and found in the malware embedding procedures or the website is a SCAM and tries to steal the information from your account. Either way, hover the link and then check to see if it's the original website that asks for credentials. In the address bar, next to the address there should be a lock. If there is no lock and the website is displaying the same information as the original one, then it shouldn't be trusted. Don't enter any passwords or vital information.
