By connecting and sharing your passport, you are sharing your verified email and/or phone number with a site which we refer to as credentials.
If you choose to remove a site from your connected sites list at any time, the site in question will no longer have active access to your credentials. That said, it’s worth noting that removing a site from your connected sites list will not automatically delete any private copies of shared email or phone number data that the site may have made on their own when you’ve actively shared your credentials.
