# Update SuperOffice username to match IdP username

> Update SuperOffice username to match IdP username

Before using a federated sign-in service, you must update each SuperOffice username to match the IdP username.

<Tip>
  The username, also known as the **User-Principal-Name** (UPN), set in your IdP must match the username set in SuperOffice Admin.
</Tip>

## Pre-requisites

* SuperOffice administrator account

* Access to view user accounts of your identity provider

The username you are going to map to is commonly (but not always) the **primary email** registered to the user account at the identity provider: `user@domain`.

## Look up the IdP username

You can find the username in the **admin>users** section.

* **For Microsoft:** Go to [https://admin.microsoft.com/AdminPortal/Home#/users][1]

* **For Google:** Go to  [https://admin.google.com/ac/users][2]

## Change username in SuperOffice Settings and maintenance

<Note>
  You **need to map each username** in SuperOffice Settings and maintenance to the federated ID.
</Note>

1. Go to Settings and maintenance.

2. Select **Users** from the navigator.

3. For each user:

   1. Select the SuperOffice user to change.
   2. Enter the new username and click **Save**.
