# Secure
|
|
|
|
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.
|
|
|
|
### Unlock sequence
|
|
|
|
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
|
|
|
|
### Automatic Locking
|
|
|
|
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](custom_quantum_functions.md).
|
|
|
|
## Usage
|
|
|
|
Add the following to your `rules.mk`:
|
|
|
|
```make
|
|
SECURE_ENABLE = yes
|
|
```
|
|
|
|
