# What is my client ID?

> How to find the client ID for an app in the SuperOffice Developer Portal.

Applications have 2 unique identifiers: client ID (`ApplicationIdentifier`) and client secret (`ApplicationToken`) . The latter is considered a password and must be stored as such.

1. In the Developer Portal, go to your app page.

   To see the list of all apps:

   * Select **Apps** from the top menu to see all apps across every partner you have access to, or
   * Go to the **Applications** section of your partner page to see that partner's apps.

2) Select **Configuration** > **Authentication**

Each application has a separate client ID for each environment (SOD, Stage, and Production).

## Regenerate the client ID

The client ID is assigned automatically and **cannot be edited manually**. Next to the client ID for each environment you have two controls:

* <i class="ph ph-copy" aria-hidden="true" /> **Copy** - copy the client ID to the clipboard.
* <i class="ph ph-arrow-clockwise" aria-hidden="true" /> **Regenerate** - generate a new client ID for that environment.

<Danger>
  Regenerating changes the identifier your integration uses to authenticate. Update your application with the new client ID afterwards, or sign-in and API calls that rely on the old value will fail.
</Danger>

## Client ID must be unique per environment

The portal validates that a client ID is not already used by another application in the same environment. If a duplicate is detected, the field shows an error and you must regenerate the client ID until it is unique before you can save:

*This Client ID is already in use by another application.*
