Good Job!!

Thank you!

Thank you!

Wonderful...

Thanks a lot!

In case someone can benefit, I used this changes:

Update woocommerce clases:

<p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide">
        <label for="reg_password2"><?php esc_html_e( 'Confirm password', 'impredecible-basoa' ); ?>&nbsp; <span class="required">*</span></label>
        <input type="password" class="woocommerce-Input woocommerce-Input--text input-text" name="password2" id="reg_password2" value="<?php if ( ! empty( $_POST['password2'] ) ) echo esc_attr( $_POST['password2'] ); ?>" />
 </p>

In case you use checkout registration add this:

Adds a confirm password field on the register form

        add_filter( 'woocommerce_checkout_fields' , 'pasword_confirmation_field_checkout' );
        function pasword_confirmation_field_checkout( $fields ) {
        
            $fields['account']['account_password']['class'] = array( 'form-row-first' );
            
            $fields['account']['account_password_ver'] = array(
                'type' => 'password',
                'label' => 'Confirm password',
                'required' => true,
                'class' => array( 'form-row-last' ),
                'clear' => true,
                'priority' => 999,
            );
            
            return $fields;
        }

Generate error message if field values are different

        add_action('woocommerce_checkout_process', 'matching_password_checkout');
        function matching_password_checkout() { 
            $pssw1 = $_POST['account_password'];
            $pssw2 = $_POST['account_password_ver'];
            if ( $pssw1 !== $pssw2 ) {
                wc_add_notice( "Your passwords doesn't match", 'error' );
            }
        }
