Facebook has strengthened email options by adding PGP encryption support via ProtonMail services as shared below



Facebook introduced email encryption back in June as a way of protecting users from getting their emails from the site hacked. The social media giant strengthened that protection this week, adding support from encrypted email provider ProtonMail.

Facebook added support for PGP encryption this June, enabling users to import their public PGP key to be able to encrypt any emails sent to them via Facebook.

Today, end-to-end encrypted email provider ProtonMail has added support for PGP encrypted Facebook emails — allowing Facebook users to get their encrypted missives automatically decrypted within ProtonMail. The feature works within ProtonMail v2.1, on both web and its mobile apps, once users have imported their ProtonMail public key into Facebook.
