How can my account details get hacked?

Every year, billions of login details from hundreds of websites are taken in hacker attacks. These stolen email addresses and passwords are then exposed on the dark web or sold on the black market, where criminals pay to gain access to your sensitive data. Companies or organizations you do business with can also leak or publish their users’ sensitive data by accident.

If criminals get a hold of one of your accounts, they can potentially impersonate you, message your contacts, access your cloud storage, steal your money, and even jump to your other accounts. That’s why we take password safety so seriously.

How can I secure my passwords?

Avast Hack Check notifies you automatically when your login details are stolen, so you can secure your accounts before anyone else reaches them. As the world’s largest consumer security company, we can securely check if any of your login details appear in our database of stolen passwords, find out if your account may have been compromised, and therefore help keep your accounts safe — and you can trust us not to save or share your email address with anyone.
