At times you may find the need to update the email address attached to your login linked to your account by a different method. This is not the notification email but a more secure email that is actually involved with the login for the merchant account identification. This would include logins for the Merchant Service Center as well as other services.
This change can be performed online from within your Intuit small business center.
Once the new email is submitted, that email will become the new login name (see note below).
This will not change your notification email.
1. Go to the accounts.intuit.com site.
2. Sign in with your Intuit Credentials.
3. Select the information that needs to be update. (User ID or Email address) After the information is updated, a confirmation email will be sent.
