Fortunately, there is a way to tell if you’ve been affected. CyberNews, who first reported the leak, has created a tool that allows you to enter your email address and find out if your login details have been compromised.

Change your passwords now, and do so on a regular basis. Try to use a combination of upper and lowercase letters, numbers and symbols. Where possible, use two-factor authentication. This involves your usual password, plus a one-time code sent to you via text message or accessed through a dedicated authentication app like Google Authenticator and Authy for added security. Enlist a password manager. Services like 1Password and LastPass cost as little as US$3 per month and will remember all your passwords so you don’t have to, meaning you can make them as complex and weird as you like.
