# Password Hashing for Windows

When creating a new Phoenix project, you can add authentication by running:

```bash
mix phx.gen.auth
```

If you do this on macOS or Linux, then Phoenix will use `bcrypt_elixir`. If you do this on a Windows machine, then it will use `pbkdf2_elixir`instead. You can find more on the pros and cons of choosing a hash system [here](https://hexdocs.pm/phoenix/Mix.Tasks.Phx.Gen.Auth.html#module-password-hashing).

Petal Pro has been pre-generated with `bcrypt_elixir` - if you're on a Windows machine, you can switch by applying this recipe. This is much more convenient than trying to compile bcrypt on a Windows machine!
