Have you been pwned?

posted December 2013

HaveIbeenPwned.com is a new website allowing you to check if your mail + password has been leak by some of those famous data breach. It's pretty bad, mine is compromised. Fortunately I use different passwords for different kind of websites. I use a garbage password for websites I don't trust, I use an easy and quick password to type for websites I don't care about, I use complicated password for more important things like my server, my steam account, my gmail account, my facebook account etc... and I regularly change them.

Well done! You've reached the end of my post. Now you can leave me a comment :)
