Can I use our existing certificate authority instead of yours?

Not today. Passbeam creates and runs a certificate authority for each client, and you can't import an external one. A certificate has to come from the authority Passbeam created for that client, or it's refused.

For most people that's what they want. Not having to run a CA is half of what Passbeam replaces, and a separate authority for each client means one client's certificates don't work on another client's network.

If you already have a PKI and a reason to keep it, tell us. It's on our list, and knowing what you need helps us decide.
