Sophos Secure Message PDF passwords

  2. Enter your email address and create your new password.
  3. In the Log in with Password section, enter the answers to up to three questions.

    You can change the questions and create your own. To do this, click on the down arrow next to one of the questions. If you forget your password, the answers to these questions are used to prove your identity.

  4. Enter an Alternate Email Address for password recovery. If you have set at least one question and answer, this step is optional.

  5. Click Apply.

Close Sophos Secure Message and return to your email software. Your encrypted email is sent to your usual email software.

You can log in any time to change your password or view your password history.
