Password Rules

The registration, profile and password reset forms use the same set of password validation rules. You can add new rules to the array from the filament-startify.php config file:

/*
|--------------------------------------------------------------------------
| Custom Password Rules
|--------------------------------------------------------------------------
|
| Set an array that's compatible with the Filament Forms rules() method.
| Rules for required and confirmed are already set. These rules will
| apply to the My Profile, registration, and password reset forms.
| If \Illuminate\Validation\Rules\Password::class instance
| fits more your needs, look inside the documentation.
|
*/

'password_rules' => ['min:8'],

Alternatively you use an instance of Illuminate\Validation\Rules\Password::class for validation, you can register new rules from the boot() method of your AppServiceProvider:

use Illuminate\Validation\Rules\Password;
use DevelogixPackages\FilamentStartify\FilamentStartify;

public function boot()
{
    FilamentStartify::setPasswordRules(
        [
            Password::min(8)
                ->letters()
                ->numbers()
                ->mixedCase()
                ->uncompromised(3)
        ]
    );
}
