You can manually enable any disabled or locked operators.
One case in which operators need to be enabled is when the Pega 7 Platform is deployed in secured mode; the administrator must enable new default operator IDs. For more information, see the deployment guide.
Click Designer Studio > Org & Security > Authentication > Operator Access.
In the Disabled operators section, select the check box next to the operator to enable.
Click Enable selected.
Click Confirm.
Note: Every operator who has been enabled must change the password when logging in for the first time.
