The secure feature aims to prevent unwanted interaction without user intervention.
?> Secure does not currently implement encryption/decryption/etc and should not be a replacement where a strong hardware/software based solution is required.
To unlock, the user must perform a set of actions. This can optionally be configured to be multiple keys.
- While unlocking all keyboard input is ignored
- Incorrect attempts will revert back to the previously locked state
Once unlocked, the keyboard will revert back to a locked state after the configured timeout.
The timeout can be refreshed by using the secure_activity_event function, for example from one of the various hooks.
