# ADA Handle Filter

{% hint style="info" %}
**Available on all tiers** — Free tier: 10 filtered actions per day, 5 allowlisted handles. Premium: unlimited. [Compare plans →](https://securitybot.gitbook.io/securitybot-knowledge-hub/plans-and-pricing/plans-and-pricing)
{% endhint %}

SecurityBot’s ADA Handle filter helps prevent phishing, impersonation, and scam attempts by blocking any **unapproved ADA Handles** posted in chat.

By default, **all ADA Handles are blocked** unless explicitly allowed. This ensures only trusted handles—such as your project’s official handles—can be shared in your community.

***

## How to Manage ADA Handles

### Enable or disable the ADA handle filter

The filter is enabled by default, meaning all ADA Handles are blocked unless approved. You can toggle the filter on or off using:

```
/settings block_handles
```

* When enabled, any ADA Handle not on the allowlist will be removed from chat.
* When disabled, ADA Handles will not be filtered.

A confirmation message will appear indicating whether ADA Handle filtering is currently **enabled** or **disabled**.

***

### Allow a specific handle

To whitelist a handle you want users to be allowed to share in chat:

```
/allow_handle [handle]
```

Example:

```
/allow_handle $securitybot
```

This adds the handle to your allowlist. Messages containing that handle will no longer be blocked.

***

### Remove a handle from the allowlist

To revoke permission for a previously approved handle:

```
/remove_handle [handle]
```

Example:

```
/remove_handle $securitybot
```

Once removed, messages containing the handle will again be blocked (if filtering is enabled).

***

### View all allowed handles

To review which ADA Handles are currently approved:

```
/chat_filters handle view
```

Select **"Allowed Handles"** from the options to view your current allowlist in an embed.

***

### Best Practices

* Only allow ADA Handles that belong to your team, partners, or trusted projects
* Use `/chat_filters handle view` regularly to audit the allowlist
* Combine with **name blocking** and **link filtering** for stronger protection
