If you receive an alert that your information has been leaked, you must change your email password and also change the password for all the accounts where you used that email to register. Many people tend to reuse their passwords - which is why it’s best to use unique ones for each account that you have.
Also, you can check the password you want to use with our password scanner that’s included in Alert to see whether that particular password has been leaked before (don’t use it if it has). If you would like more information, you can always contact our friendly support team, and we’ll help you figure out if you need to do anything else to secure your accounts.
