global variable

Hello ,
First thank you to all team worked in this fantastic framework, 
I have
$password = array(
        'cansave' => true,
        'Algorithm' => 'abc'
);

I want to access $password from many models I use modules\user
I tried many ways to save it in new class , other ways , but I couldn't access it from usermodel that I have.
I'm not professional developer , that is why help file not helping much , if possible step to access it will be nice.

Thank you in advance.
