Secret Codes is an Open Source application allowing you to scan the secret codes available on your android device through the dialer app and discover hidden functionalities.
I propose that there should be security measures to protect private and confidential codes from being accessed by others. The developers of the Secret Codes application should add a "lock" feature so that users can lock and keep private information and secret codes from intruders.
This security option should be created whereby a user will need to input a password or pin for the application to be effective.
Introducing this feature, users will feel safe because private and secret codes on their devices will be secured from unknown individuals.
