Has Your Password Been Leaked?
Billions of passwords have been stolen in breaches and published in lists that criminals run against business email accounts every day. Type a password below to see if yours is on one of those lists. It takes about two seconds.
Check a Password
Your password is hashed on this device. Only five anonymous hash characters are checked, and nothing is stored.
How this works, in plain English
Your password never leaves this device
It's scrambled in your browser first. Only five characters of the scrambled version are sent, which matches thousands of different passwords at once — so nobody, including us, can tell which one is yours.
"Found" doesn't mean you were hacked
It means this exact password appeared in a breach somewhere in the world. If you use it anywhere, attackers already have it on a list they try automatically.
What to do if it shows up
Change it everywhere you used it, starting with email and banking. Then stop reusing passwords — a password manager handles this so you don't have to remember anything.
