Facebook says users can add OpenPGP public keys to profiles, enable encrypted email notifications

Starting today, Facebook users can list their OpenPGP keys on their profiles to enable encrypted email notifications.

In a public post, Facebook called the feature “experimental.” Once activated, users will be able to send end-to-end encrypted notifications emails from their Facebook profile to email accounts.

If a user enables encrypted messages but does not add an OpenPGP key, then Facebook will encrypt the messages using its own key.

For now, the feature can only be managed via desktop.

“To enhance the privacy of this email content, today we are gradually rolling out an experimental new feature that enables people to add OpenPGP public keys to their profile; these keys can be used to ‘end-to-end’ encrypt notification emails sent from Facebook to your preferred email accounts,” the company wrote. “People may also choose to share OpenPGP keys from their profile, with or without enabling encrypted notifications.”
