Domain Management Guide

## Overview

This guide explains how to turn on or off (lock or unlock) domain **Registrar Lock** in the [client portal](https://bestnetllc.co.jp/en/encyclopedia/client-portal-en/).

When you turn on Registrar Lock, you can help prevent unauthorized domain transfers by third parties. If you need to transfer your domain, please change it to **off** beforehand.

   STATE 1 **On**

Helps prevent unauthorized transfers by third parties. This is recommended for normal operations.

   STATE 2 **Off**

This setting is required before performing a domain transfer (Transfer Out).

   POINT **Confirm after changes**

Verify that the save success message appears and the domain details display has been updated.

## Cautions

   **On is recommended during normal operations**

For security reasons, we recommend keeping Registrar Lock **on** during normal operations.

   **Change to off before transfer**

If you need to transfer your domain, change it to **off** before starting the transfer process, and change it back to **on** after the transfer is completed.

   **Propagation may take time**

Depending on the registry’s processing status, status changes may take time. If the display does not update, please try refreshing or reloading the page.

## Troubleshooting

### No success message appears after saving / the status does not change

- Please refresh or reload your browser.
- There may be a temporary communication or session timeout issue. Please log in again and try again.
- If the issue persists, please contact support with a ticket including the “target domain name,” “date and time of attempt,” and “desired status (on/off)”.

### I cannot find the Registrar Lock change option

- If the domain is not active (pending approval / in transfer, etc.), it may not be displayed or changeable.
- Depending on the target TLD or registrar specifications, there may be restrictions on portal operations.
