Password or lock to access for security reasons feature

`Hi,

First, thanks for the solution. Is amazing!

I would know if the plugin have a feature to lock, set up passaword or limit access for user roles.

I has been hacked before and even though the alleged hacker can access the admin profile, he will still be able to edit the snippets in php. I need to set a limit for these cases of access in the admin area, so that access to the edition will be only allowed after password authentication or something like that

Is possible?
