Password field - field functionality

Today i looked at the “password” field.

When i create or edit this field in object i can use this button image and it randomly add some new password. It is great.

But i should to have possibility customize create random password, as example in terms of :

  1. quantity of characters
  2. password mask - like special characters i want to use in create random password and which exactly; great and litlle leters; numbers

I also checked created object with “password” field from the database side and i saw that the value of “password” field is not hiding/hashing. I see password which I wrote in object.

Is should be that?
