# Regenerate outbound trunk credentials

Replace the SIP digest password for a trunk that uses **Credentials &
IP-Based** authentication.

## Before you begin

- An active DIDWW account is required. [Sign in to DIDWW](https://my.didww.com/users/sign_in).
- An existing outbound trunk using **Credentials & IP-Based** authentication
  is required. [Create an outbound trunk](create-outbound-trunk.html) or [Edit an outbound
trunk](edit-outbound-trunk.html)
  if you need to create or switch to this method.

## Step 1: Open the SIP Credentials window

1. In the DIDWW User Panel, go to **Voice > Outbound Trunks**.
2. Locate the trunk and click the key icon in the **Credentials** column.

## Step 2: Regenerate the password

Click the regenerate icon next to the password field to generate a new
password immediately.

Warning

Regenerating replaces the password immediately. The previous password no
longer authenticates requests. The username does not change. Update
every system that uses the trunk with the new password at the same time
you regenerate it, as described in [Credential
lifecycle](../authentication-security.html#outbound-trunk-credential-lifecycle).

Field definitions are listed in [Credentials window
fields](../outbound-trunk-reference.html#outbound-trunk-credentials-fields) in the Outbound trunk reference.
