Well it's not secure if you just typed a PW into that website because it is now recorded/logged together with your IP address.
How many gullible people have used this site to type in their true passwords used for banking, credit cards etc and then had them recorded by this site to be used later. Which Russian mafia group set this website up? Oh I'm sorry. Only honest people are allowed to have websites. LOL!!!!!!!
Be warned. Do not go to websites like www.howsecureisyourpassword
(there are others) because they are a major security risk to you and certainly do not go typing your passwords into them.
