At some point we have all been guilty of this, reusing passwords on multiple sites because it is impossible to remember every password for every website we are required to log into these days! I personally used to think having a password manager was bad, but it isn’t!!! Password managers enable you to use features like, generating secure passwords. It remembers them for you, so you don’t have to rely on your memory or sticky notes around your computer! Just make sure you password manager has a secure password!!!
Troy Hunt teaches courses on Pluralsite.com and is an Australian Microsoft Regional Director and also a Microsoft Most Valuable Professional for Developer Security. (from his website!) He’s an expert on this!!!! He has a website called, haveibeenpawned.com and he uploads security breach information to a database and then all you have to do is put your email address in and it searches to see if you have been pwnd. Pwnd meaning that your security credentials have be compromised. I recommend you visit it ASAP! You will be shocked and I guarantee you will start changing many of your passwords!!!!! It’s a free service he provides and it’s a ton of work!!!! I highly recommend donating money to the site. It’s a ton of work he is doing to keep us safe. 🙂
I recommend you read his blog post about passwords and password managers. He has listed a few that are very good. Check the post out here.
