TWILIO: Authentication tokens and how to change them

Estimated reading: 3 minutes

Twilio uses two credentials to determine which account an API request comes from: the account SID, which acts as the username, and the Auth Token which acts as the password. This guide explains how to find your Auth Token, and how to change it.

Where is my authentication token?

You can find your authentication token in the Info pane of the dashboard.

The authentication token for your account is hidden by default. Click on Show to display the token, and on Hide to hide it again.

What is a secondary authentication token?

A secondary authentication token is a backup of your primary authentication token. The secondary token works the same way as your primary token and can be used to keep your applications running during a token rotation. This allows you to switch your services from one token to another without service interruption.

When ready, secondary tokens can be promoted to primary token, replacing the previous primary token.

How can I change my authentication token?


1. Go to the page Account > API keys and tokens in your console.

2. At the top right, select the region for which you want to modify the authentication token:

3. Scroll down the page to the section Auth Tokens, then click on
Request a secondary token












4. In the dialog box, click Request token.








5. Click on the icon to display your new secondary token, and use it to update your existing Twilio applications. Make sure your applications are updated with your new secondary token before promoting it.

6. Click on Promote to Primary to make your newly created authentication token the primary token of your account. A dialog box will appear asking you to confirm the consequences. Once confirmed, the old primary token will stop working.
