A cloud-based identity and access management service for securing user authentication and resource access
Hello,
Thanks for the post! Can you confirm which form you were filling out for which product?
In PearsonVue, all learners that doesn’t have any last name should use underscore ( _ ) as the replacement on the require field. Please note though that if this is related to PearsonVue certification scheduling, Microsoft Certification / Training is supported on their own forums. I'd try asking for help with exam scheduling / vouchers in dedicated forums here. (Participate\Ask A Question)

For other services, the protocol may vary product by product.
