# How-To: Unmatch Accounts

> Unmatch an account that was matched to the wrong Lumos User, then rematch it, and learn why accounts linked to User Sources cannot be unmatched.

## After this article...

You'll know how to unmatch an account that has been incorrectly matched to the wrong User in Lumos.

## When would you need to unmatch an account?

The Lumos automatic **matching logic** ([*How does Lumos match accounts?*](/for-admins/applications-entitlements/how-does-lumos-match-accounts)) matched something incorrectly, or you made a mistake when **manually matching** ([*How-To: Match Accounts*](/for-admins/applications-entitlements/how-to-match-accounts)).

## Steps

**1. Find the account you want to unmatch**

**2. Click the "..." button in the \_Action\_column, then choose the "Unmatch Account" option.**

If the unmatch is successful, the account will no longer be matched to a Lumos User and will be labeled "Unmatched".

Once you've unmatched an account, you can manually match it again to a new User following the steps here:[How-To: Match Accounts](/for-admins/applications-entitlements/how-to-match-accounts)

## Troubleshooting

### Lumos won't let me unmatch an account.

Accounts linked to your **User Sources** cannot be unmatched. *See[Source of Truth](/for-admins/applications-entitlements/source-of-truth)*

If you need to unmatch accounts tied to your user sources, contact Lumos Support at [support@lumos.com](mailto:support@lumos.com) with a description of your use case.
