I think an optional extra protection for some of the logins, eg. banking sites, or on anything the user wants to add extra protection would be great to have in the Norton products.
I imagine the function this way:
I. Configuring the extra password
1. Open Identity Safe's Logins list from settings
2. Go to the Login you want to add the extra protection
3. Check the checkbox for secondary password
4. Write the password in (in a new window, or into a textbox that was enabled when you clicked the checkbox in)
5. Save settings
II. Using in the browsers
1. Select the login from the toolbar's list
2. When the page is loaded a window (or something) comes up where you can write the extra password in
3. When you select OK and the password is right the forms can be filled, else it will be blank
And the program should check the normal and secondary passwords, that they should not be the same.
