If someone sends you an encrypted email using portal encryption, you must log in to Sophos Secure Message to see it. Sophos Secure Message is a secure web-based email client.
The first time someone sends you an encrypted email using this method, an account is created for you in Sophos Secure Message. The account uses your email address. You receive an account activation email in your usual email software. You must activate the account to read your encrypted email. See Activate your Sophos Secure Message account.
After you have activated your account, when people send encrypted emails to your Sophos Secure Message account, you receive notification emails in your usual email software. You click the link in the notification emails to log in to your account.
You use Sophos Secure Message to read and reply to encrypted emails, and manage your account. See Using Sophos Secure Message.
If you forget your Sophos Secure Message password you can recover it. There is a link to the recovery process in the notification emails you receive each time someone sends you an encrypted email. See Recover your password
