Symptoms
A customer wants to change login name for a staff member in their account.
Resolution
Since OA version 7.0 it is possible to change login in UX1 of reseller or end-customer:
Login to UX1 (CCPv2)
Click to your user name in top left corner, then click My Profile > User Settings > Edit
- Change login in field Email (To Sign In) and click OK
Note: It is possible to change user's login name using BA API method UserUpdate_API.
However, after using the mentioned above API method user login will be different in BA and OSA, it will lead to inability to log into OA Control Panel.
