This is primarily for creating new login for new apps that need a secure password. Maybe even for changing the password on existing apps.
When creating a new login and password for a new app or new website while using the mobile app, it would be nice to have included in the autofill pop-up, a "generate password" function. Sometimes switching over to the Last Pass app causes the new app to lose its place and consequently creates a small whirlwind of activities in order to get back to the new login screen. This could be alleviated by putting the option in the autofill popup with an option for generating a secure password. It might need to be a bit more elaborate, as switching back and forth to get the new login saved could result in a set of routines that could get confusing, so it might need a way of capturing the login information during the login creation (like with websites) that asks you to create a new login.
