Hi Rafael,

This is an email to help you enable encrypted notification emails for your Facebook account.

If you prefer to not enable encrypted notification emails from Facebook, you may simply 
ignore this message.

If you enable encrypted notification emails, Facebook will begin encrypting notification
emails to you with your public key. These may include account recovery notification emails.

BEWARE: If at some time in the future you cannot decrypt your account recovery notification
emails and if you also become locked out of Facebook, you may be unable to recover your
Facebook account.

To proceed with enabling encrypted notification emails, please click this link:
