Make sure that you verify your CPI identity periodically to show that your
credentials are still valid. To verify your identity as a CPI, follow these steps:
On the right, select your Google Account, and then click Verify CPI identity.
Enter your CPI ID, Certificate, and Certificate password.
Click Verify.
The SAS Portal validates that you are a CPI by encoding a random
string that uses your certificate file and password. It also decodes the string with
the corresponding public key in the
WInnForum CPI database.
The validation takes
place locally in the browser, so your certificate file stays on your computer.
After your CPI identity is verified, repeat step 4 and sign off on any
additional CBSD configurations.
