# Lock a firewall

Lock a firewall to keep anyone on your team from changing it by mistake, for example a firewall in
production. A locked firewall keeps running and passing traffic. Only its MyAccount actions
are blocked until you choose **Unlock Firewall**.

While the firewall is locked, **Start**, **Power Off**, **Reboot**, **Reinstall Firewall**,
**Upgrade Firewall Plan**, and **Delete Firewall** are greyed out, and the rename pencil is hidden.
To attach or detach a VPC or an Add-on IP, choose **Unlock Firewall** first. While it is locked, a
VPC change shows **VPC cannot be attach/detach in Locked State.**

To block only delete and reinstall, while the other actions stay available, use accidental
protection instead. See
[Turn on accidental protection for a firewall](/myaccount/firewall/how-to/turn-on-accidental-protection-for-a-firewall/).

## Before you begin

- The firewall has finished any change in progress, such as **Creating** or **Upgrading**.
- Your role in the project can update firewalls.

## Lock the firewall

1. In MyAccount, under **Network**, click **Firewall**.
2. On **Manage Firewall**, in the firewall's row, click **Actions**, then **Lock Firewall**.
3. In **Lock Firewall**, confirm.

**Firewall locked successfully** shows.

## Check the lock

Open the firewall's **Actions** menu. **Unlock Firewall** shows in place of **Lock Firewall**, and
**Start**, **Power Off**, **Reboot**, **Reinstall Firewall**, **Upgrade Firewall Plan**, and
**Delete Firewall** are greyed out.

## Unlock the firewall

When you are ready to change the firewall again:

1. On **Manage Firewall**, in the firewall's row, click **Actions**, then **Unlock Firewall**.
2. In **Unlock Firewall**, confirm.

**Firewall unlocked successfully** shows, and each action is available again whenever the
firewall is in the right state for it, such as **Power Off** while it is **Running**. For the state
each action needs, see
[An item in the Actions menu is greyed out](/myaccount/firewall/troubleshooting/firewall/#an-item-in-the-actions-menu-is-greyed-out).
