Hi all,

We send Firebase app invitations only to our company domain emails, but the invitation email can be forwarded and accepted by a personal Gmail account, which creates a security concern.

Is there a way to:

Restrict invitation acceptance to only the Google account that received the email

Or limit access to company-domain Google accounts only

Prevent forwarded invitations from granting access to unauthorized users

Any best practices or Firebase-supported solutions would be appreciated. Thanks!
