Password breach checker
Check if your password has been leaked.
How we keep your password protected
This tool is all about making sure your password isn't leaked, and we want to keep it that way. Your password is never sent to our servers. Here's how:
When you type in a password in the input field, we use theSHA-1algorithm to hash your password.
We then send only the 5 first characters of that hash to our API, which returns a list potential hashes.
That list is then compaired against your full password hash, and if one is found, there's some extra information about how many times that hash has been registered inHIBP's dataset.
This ensures that your password is never actually sent over the internet.
You can verify this by looking at the request send tohttps://devina.io/api/password-breach in your browser console.
