Help me out with your opinions guys! I need to make a mockup of how my password/unlock feature will be laid out and I need some help thinking about how it should be or the gist of it. There's going to be an option to set the password, an option to change it, and some sort of indication that the password is set. After the password is intitially sey, the set button would never be able to be used again, as it would strictly rely on the change button if it needed be changed or set again. So what I am thinking is that the set password would turn into some sort of notification box with the asterisks or bullet dots indicating that a password is set. Then under that box would be the change password box. Also, how many characters do you think should be required? 6? It's a pretty simple unlock feature, the password unlocks the block feature of my app.
