I’ve said it before and I will say it again, it is EXTREMELY important to create strong passwords for every site you log into, especially your website. Here’s a great quote on why from Wordfence:
The issue is that many users have the bad habit of using the same password across multiple websites and that’s why the hacker grabbed your password file and is throwing significant resources at brute-forcing it: So that they can gain access to the real treasure-trove of Gmail accounts, LinkedIn, Facebook, Hotmail, Quicken, Paypal, eBay and all the other valuable accounts out there that let them steal real money from real people who are members of your website.
If a hacker gets into your site and gains access to your passwords, they most likely just gained access to your bank, your email, etc, etc. It’s a scary thought it happens all the time.

And CHANGE YOUR PASSWORDS!
