Sidekick

Security Pin

This command will set a security pin required before all communication.

To set a security pin, you would instruct Sidekick   q security [pin] with [pin] replaced by a valid numerical code. You can set the pin to 0 in order to delete it.
Sidekick will initiate a multi-step process to confirm it is you and verify the desired security pin.

Once the pin is set, you will need to enter it on the first line of the message body by itself and then your communication on subsequent lines.
