GlobalSign's hassle-free SSL certificate installation doesn't just make it a breeze for certificate issuance, it also ensures your certificates are trusted by 99.9% of devices connected to the web. But sometimes, unforeseen circumstances can require manual validation. Here's where understanding the 'R2' and 'GFPCA' comes into play.

Understanding GlobalSign R2 (Right to Reply)

GlobalSign's R2 or 'Right to Reply' is a feature that lets subscribers validate the usage of GlobalSign's non-public root certificate 'GFPCA'. When you install a GlobalSign certificate, R2 is triggered, providing you with an R2 event (or 'GFPCA' error) that needs to be acknowledged.

The R2 event is an essential part of GlobalSign's commitment to maintaining internet security. It's GlobalSign's way of ensuring that the certificate is being used appropriately and isn't being misused for malicious activities.

GlobalSign R2 Non-Public Root Certificate - GFPCA

The 'GFPCA' root certificate, also referred to as GlobalSign's non-public root certificate, is installed on the GlobalSign public certificate chain. It's non-public, meaning it's not distributed to end-users; it's only distributed through Windows Update and Apple's root certificate server, ensuring no misuse can occur from external sources.

Upon installing a GlobalSign certificate, the 'GFPCA' root certificate auto-populates in your system's trusted root certificate store, triggering the R2 event, which requires validation of its use.

Navigating the GlobalSign R2 Process

When you install a GlobalSign SSL certificate, you may encounter the R2 event, where you'll need to confirm whether you're the party directly associated with the public certificate being distributed. If so, you'll indicate your 'right to reply' or acknowledge the usage of the certificate.

Don't worry if you didn't initiate this request. In such cases, simply deny the request, and GlobalSign's support team will look into it, ensuring there's no misuse of the certificate.
