Security Words
Silent Phone's Security Words put you in control of your own security. This unique system forms a "last line of defense" to keep man-in-the-middle attackers out of your communications. It's just one way that we go the extra mile to protect our customers. Here are the three steps to make your calls extra secure.
-
Observe
On a call, you'll be prompted with two Security Words.
-
Compare
Both you and your partner should read both words to each other. Be sure that you both see the same words on the screen.
-
Verify
Tell Silent Phone that you have compared the words and that they match. Silent Phone will show that the call is "Green Secure" and will remember this for the next call. You only have to do this verification once per pair of devices.
