When sending a secure email to your recipient, you'll be prompted to choose between the following authentication challenges:
Option 1. SMS Challenge
Automatically sends a 6 digit code via SMS to your recipient's mobile phone when you send the message. They are then prompted to enter this code when opening the message.
Option 2. One-time code via email
When the recipient starts to open the message they will be sent an email containing a 6 digit code. They then enter this code to unlock and view their secure message.
Option 3. Question & Answer Challenge
Set your own question and answer to secure the message. The recipient is then shown the question and must enter the answer before they see the contents.
The question and answer you set are critical to the security of the message, so here are some tips to help you create a secure question.
With all authentication challenges, recipients will have 5 attempts to enter the correct code or answer. If they are unsuccessful, the secure message will be automatically revoked, and both the sender and recipient will receive a notification informing them of this action.
