Reset Password policy

Question

Looking for to add reset password policy.

Password specifications :

12 characters in length, 1 uppercase letter, 1 lowercase letter, 1 number, and 1 special character.

I find a hooks for manage policy to change user password on the backoffice :

add_action( 'resetpass_form', function( $user ) { ?> <p class="user-wpse-pass2-wrap">
        <label for="wpse-pass2"><?php _e( 'Confirm new password' ) ?></label><br />
        <input type="password" name="wpse-pass2" id="wpse-pass2" class="input" 
               size="20" value="" autocomplete="off" />
    </p> <?php } );

add_action( 'validate_password_reset', function( $errors ) {
    if ( isset( $_POST['pass1'] ) && $_POST['pass1'] != $_POST['wpse-pass2'] )
        $errors->add( 'password_reset_mismatch', __( 'The passwords do not match.' ) ); } );


function validate_password_reset ($Password) {
    //#### Check it's greater than 12 Characters
    if (strlen($Password) < 12) {
        return "Password is too short (" . strlen($Password) . "), please use 12 characters or more.";
    }

    //#### Test password has uppercase and lowercase letters
    if (preg_match("/^(?=.*[a-z])(?=.*[A-Z]).+$/", $Password) !== 1) {
        return "Password does not contain a mix of uppercase & lowercase characters.";
    }

    //#### Test password has mix of letters and numbers
    if (preg_match("/^((?=.*[a-z])|(?=.*[A-Z]))(?=.*\d).+$/", $Password) !== 1) {
        return "Password does not contain a mix of letters and numbers.";
    }

    //#### Password looks good
    return true; }

I want to add the same policy for reset password on login page like for this site!

Thanks.
