.NET Standard library that provides client SDK functionality to talk to Troy Hunt's Pwnedpasswords API and check whether a particular password has been pwned and if so how many occurrences there have been.


ByteDev.PwnedPasswords has been written as a .NET Standard 2.0 library, so you can consume it from a .NET Core or .NET Framework 4.6.1 (or greater) application.

ByteDev.PwnedPasswords is hosted as a package on To install from the Package Manager Console in Visual Studio run:

Release Notes

Releases follow semantic versioning.

Full details of the release notes can be viewed on GitHub.


The PwnedPasswordsClient class has two public methods:

  • GetHasBeenPwnedAsync(string password)
  • GetHasBeenPwnedAsync(string password, CancellationToken cancellationToken)

These methods will return a PwnedPasswordResponse object containing details of whether the password has been pwned and a count of how many times.

If the PwnedPasswordsClient class has any problems getting the details for a password it will throw an PwnedPasswordsClientException.

IPwnedPasswordsClient client = new PwnedPasswordsClient(new HttpClient());

PwnedPasswordResponse response = await client.GetHasBeenPwnedAsync("Password1");

Console.WriteLine($"Has Password been pwned: {response.IsPwned}.");
Console.WriteLine($"Password has been pwned {response.Count} times.");
