# Backup numbers

Backup numbers protect your WhatsApp groups. If your main number is blocked or banned from a group, you lose access permanently unless another admin is present. Backup numbers are added as group admins so you always keep control.

A backup number does **not** need to be connected to BatZap. Any trusted WhatsApp number works.

## How backup numbers work

When you create a new group, all active backup numbers are pre-selected and added as group administrators. You can deselect any of them for a specific group without changing your backup list.

## Add a backup number

1. Go to **Settings → Backup Numbers**.
2. Enter the phone number in the field (any format works).
3. Click **"Add Backup Number"**.

## Manage backup numbers

Each number in the list has an **Auto-Add** toggle:

- **On**: the number is automatically added as an admin to every new group.
- **Off**: the number stays in your list but is not added automatically. You can still select it when creating a group.

Use the delete action to remove a number from the list.

The footer shows a summary, for example how many numbers are registered and how many have auto-add enabled.

## Good to know

⚠️ Backup numbers are added when a group is **created**. Existing groups are not updated automatically.

💡 Deselecting a backup number while creating a group only affects that group. It stays in your backup list for future groups.
