Should require user provide master password when view/copy password field or key of TOTP

[Binh Truong 12]

Currently Enpass support Generate TOTP and user can view password. 

When we use extension for browser and it is not always we must protect Enpass extension when someone borrow our PC for some minutes and they try view password or TOTP key by edit field.

So I suggest Enpass should require user enter master password again when user view/copy password or secret key of TOTP, of cause we allow user some option after enter master password to view password as after 15 mins/1hours/until reboot PC/Until user active again.
