Use of buttons

A project log for Key Pass

Keychain USB multiple password manager/generator/injector

I've been considering about removing both buttons and using [NUM LOCK] and [SCROLL LOCK] for changing the slot and sending the password, respectively. In this case a hidden reset button would place the microcontroller in bootloader mode.

On the other hand, without buttons I would not be able to use the Key Pass in devices without keyboard, like tablets and phones.

Maybe the best solution for now is to allow the change of slot by either pressing [select] button or [Num lock] on the keyboard, and sending (typing) the password either by [send] button or by [Scroll Lock] key.

Well, I was planning only the large USB version, used with an adapter cable (like USB OTG). The small USB plug might me tricky to find, and I think it is a bit fragile.
I've been also wondering about using only one button, where a short press could select the slot and a long press could type the password.

Ah, that's a great point. I do like the press length selection variation!

If you're planning on using it for tablets and phones, would you make a version with a micro connector? If so, it'd be neat to have that with buttons, and the larger USB version button-less.
