Submitting the iOS Development Certificate Signing Request

Having created the Certificate Signing Request (CSR) the next step is to submit it for approval. This is performed within the iOS Provisioning Portal which is accessed from the Member Center of the Apple developer web site. Under Developer Program Resources on the main member center home page select iOS Provisioning Portal. Within the portal, select the Certificates link located in the left hand panel.Click on the Request a Certificate button, scroll down to the bottom of the text under the heading Create an iOS Development Certificate and click on the Choose File button. In the resulting file selection panel, navigate to the certificate signing request file created in the previous section and click on Choose. Once your file selection is displayed next to the Choose File button, click on the Submit button located in the bottom right hand corner of the web page.
At this point you will be returned to the main Certificates page where your certificate will be listed as Pending Approval:
If you are not the Team Administrator, you will need to wait until that person approves your request. If, on the other hand, you are the administrator for the iOS Developer Program membership or have administrative privileges, you may approve your own certificate request by clicking on the Approve button located in the Action column of the Your Certificate table. Your certificate is now active and the table will refresh to include a button to Download the certificate.
