What happened in the 1win breach?

1win (1win.com) was hit by a data breach dated November 2024, exposing around 96 million accounts. Incidents like this happen when attackers break into a company’s user database, or when a misconfigured server or third-party partner leaks it — and the stolen records then spread among other criminals.

The exposed records included dates of birth, email addresses, geographic locations, ip addresses, passwords and phone numbers. Leaked data doesn’t simply disappear: it gets copied, sold and re-posted across breach forums and dark-web markets for years. That’s why your information from the 1win breach can still be abused long after the original incident — and why checking your exposure and locking down your accounts matters even now.

What data was exposed in the 1win breach?

The 1win breach exposed dates of birth, email addresses, geographic locations, ip addresses, passwords and phone numbers. The more of these are tied to you, the more ways an attacker can impersonate you or break into your other accounts.

How the leaked 1win data can be used against you

Because the 1win breach exposed dates of birth, email addresses, geographic locations, ip addresses, passwords and phone numbers, the leaked passwords let attackers try the same login on your other accounts (credential stuffing), so any site where you reused it is at risk; your email address becomes a target for convincing phishing, often referencing this very breach to look legitimate; your phone number fuels scam calls and smishing (fraudulent texts); and your address can be used to locate you, sold on to people-search sites, or used in doxxing.

How to check if you were affected

The leaked records themselves aren’t published openly, so the way to know is to check your email against known breach and dark-web databases. Our free tool does exactly that in a few seconds — no account needed.

What to do if your 1win account was breached

These steps are prioritized for exactly the kind of data the 1win breach exposed.

1
Change your password — and anywhere you reused it

Reset your 1win password now, and change it on every other account where you used the same one. Reused passwords are how a single breach turns into a chain of account takeovers, so give each important account its own strong password (a password manager makes this painless).

2
Turn on two-factor authentication

Add 2FA — ideally an authenticator app or a passkey rather than SMS — to your email, banking and other important accounts, so a stolen password alone can’t get in.

3
Expect spam calls and scam texts

Leaked numbers feed robocalls and smishing. Never act on an unsolicited call or text, enable your carrier’s spam filter, and remove your number from data-broker sites that resell it.

4
Limit your address exposure

Exposed addresses spread to people-search sites that anyone can look up. Opting out of data brokers makes your home harder to find and lowers your doxxing risk.

5
Watch for targeted phishing

Scammers reference real breaches to sound credible, so treat any email mentioning 1win with suspicion, and never use a password-reset link you didn’t request — go to the site directly instead.

6
Monitor whether your data resurfaces

Leaked data is resold for years, so a one-time clean-up isn’t enough. Ongoing breach and dark-web monitoring tells you the moment your details reappear, so you can act before an account is misused.
