Data breaches: your password is already out there

Billions of passwords have leaked. If you use the same one everywhere, hackers automatically try it on all your other accounts.

Updated: 2026-10-17

1How they do it

  1. A website you once used gets hacked. The email addresses and passwords end up online.
  2. Hackers automatically try those combinations on thousands of sites (credential stuffing).
  3. If it works somewhere, they take over your account: email, online shop, social media.
  4. With your mailbox, they then reset other passwords.

2A real example

You used "Zomer2019!" for a fitness app that was hacked. A month later, someone is shopping with your online shop account.
