Want to add a tip of my own, that I tend to use whenever I'm unsure wether a site is real or not:
Inspect element (ctrl+shift+c) on the site you're suspicious of, then search (ctrl+f) type in ex: ' method=" ' If it says something.php it's likely a phishing site. Most commonly you'll see post.php and send.php on phishing sites..
method="post" means the form information is being sent via POST (there is also GET). This is just the way the website gets the information from the submission form when you login -- it is in no way strictly something used by phishing sites. and then theres also the action="./blah.php" which is where you will be redirected and the information sent to after clicking the submit button on the form. again, this is used on every website..
