U2F not working at all

[brneor]

Describe the bug.

When I access the "U2F" app, I'm briefly presented with the message "Connect to a device" and then "Connected!", but after a couple of seconds it goes back to "Connect to a device". If I do the same but it's not connect to any USB device, it keeps saying "Connected".

Reproduction

1. Just open the U2F app.

Target

No response

Anything else?

I'm on latest stable firmware, 0.103.1. Tried to reboot, reinstall firmware and even a custom firmware, same issue.

Greetings. What firmware version are you using and what OS?

Just tried Mac/Win11 on latest release / latest dev and see no issue. In a bit will try on Ubuntu

Edit: saw the firmware version. Just curious about OS now

@doomwastaken I have to apologize. Even though the Flipper is saying "Connect to a device", it is working properly when I try to use it (tested with this website).

Is the message "Connect to a device" an expected behavior in this scenario? I tested in a Windows 11 and a macOS 14 machine, both showed the same behavior.

Trying same thing on windows at this second.

U2F open, USB cable not plugged in. Site is open and on "Insert or tap your YubiKey" Separate window promt appears to connect external device to USB key, clicking ok Plugging USB cable Flipper says "Press OK to register" Clicking ok then leads yubico registration complete and u2f app asks to be connected to device (USB cable plugged in) Clicking authenticate on website instantly makes flipper go into "Press ok to authenticate" Unplugging cable here works fine, re-plugging cable sends it to connected -> "Press ok to authenticate" on flipper.

Is that same behavior for you? Only part that I am not certain is behavior after registration, maybe app should state that it is connected, rather than "connect me to a device". Other than that, app works just fine on Mac/Ubuntu/Win10/Win11 that I had available for tests.

Once I check the behavior of an app according to our design guidelines, I will get back to the ticket

Yep, the behavior is almost the same, except that my Flipper says "Connect to a device" all the time even if it's connected and sometimes says "Connected" when not connected. That was the culprit of my confusion.

[doomwastaken]

I've encountered that behavior once, in firmware 0.92 or so, however device reboot fixed it and I was never able to reproduce it. Either way, I had opened a ticket, we will get back to you once it is merged into dev

Ty for your attention!
