How does PH know I used the same password on another site?

Does PistonHeads have a "Support Center"?

It's a feature provided by PH's authentication provider who track large security breaches that occur on major third-party sites.

Password hashes.

Bet if you go to https://haveibeenpwned.com/Passwords and pop your PistonHeads password in it'll feature somewhere else where you use the same password.

It’s not the most secure of passwords, had it since the beginning when life was simpler!!

Thanks for prompt responses - (post was public as I thought it may be of interest)

Stock answer on this stuff is get yourself a password manager and use strong long unique passwords for every website you use and enable 2FA where possible.

Prioritise the things that can mess up your real life i.e. your email provider and social media.
