One Reused Password Can Sink Everything

Hackers don't guess passwords. They take the one you used on some random site in 2019 and try it on your email and bank. It works constantly.

THE ONE RULE

One site, one password. And turn on two-factor everywhere.

A password manager remembers hundreds of unique passwords so you don't have to. Two-factor authentication means a stolen password alone is useless. These two things stop most account takeovers cold.

1 How it works

1

Some website gets breached

A forum, a shopping site, an old app. Your email + password leak into criminal databases along with billions of others.

⬇️
2

Bots try that combo everywhere

Automated tools test your leaked password on Gmail, banks, Amazon, Netflix, everything. It's called credential stuffing, and it runs 24/7.

⬇️
3

Reuse = master key

If it's the same password, they're in. Email is the jackpot: with your inbox, they reset every other account you own.

⬇️
4

Infostealers make it worse

Malware harvests every password saved in your browser at once. About 1 in 5 break-ins uses stolen credentials.

2 Red flags

🚩
You use the same password (or Password1 / Password2 variants) on multiple sites.
🚩
Your passwords live on sticky notes or in one "passwords.docx" file.
🚩
No two-factor on your email or bank.
🚩
"Password reset" emails you didn't request. Someone is trying the door.

3 Protect yourself

Get a password manager (we set these up all the time). One strong master password, unique everything else.

Two-factor on email and bank first, then everything. An authenticator app beats text codes.

Check yourself at haveibeenpwned.com. See exactly which breaches leaked your info.

Use passkeys where offered. Nothing to steal, nothing to reuse.

4 Already happened? Do this now

  1. Change your email password FIRST. It's the key to everything else.
  2. Then bank, then everything sharing the old password.
  3. Turn on two-factor as you go.
  4. Check your email for forwarding rules you didn't create. Attackers hide there.
