Differences between Onlykey and Onlykey Duo

[NathanaelA]

Is there any differences (besides 3 buttons w/ long presses instead of 6) between the original and this one?

The kickstarter info didn't really lay out if there was any new changes or limitations vs the original in the smaller form factor?

The main features are essentially the same just with a smaller form factor that supports USB-C and USB-A. Both OnlyKey and OnlyKey DUO will run the same firmware. There are some differences such as OnlyKey DUO has 4 profiles each with 6 accounts (OnlyKey has 2 profiles each with 12 accounts). In order to access OnlyKey DUO you can have no PIN, PIN entered via App, or PIN entered on device (OnlyKey only has PIN entered via device). OnlyKey DUO has one PIN to unlock device then hold button #2 to switch between profiles (OnlyKey has two PINs, one for primary and one for secondary profile, there is no switching between profiles).

... OnlyKey DUO has one PIN to unlock device then hold button #2 to switch between profiles (OnlyKey has two PINs, one for primary and one for secondary profile, there is no switching between profiles).

Does the user need to keep pressing button #2 in order to go through profiles in sequence? If so, wouldn't it be better (and faster) to long-press button #2 once to initiate the profile changing function; and then pressing a number 1-4 to go directly to that profile?

And what about the processing power? Is Onlykey duo faster than the original?

It would be short and long press on all buttons. Hold #2 for 5+ sec to switch profiles. Hardware processor is the same as OnlyKey.
