[feature request] react to OATH requests #35

Open ftpd opened 2 years ago

ftpd commented 2 years ago

Hey. Is it possible to add reaction to OATH module? For example, I would like to get notification after ykman oath account code <service name>.

maximbaz commented 2 years ago

Hey, I don't use OATH, could you help me with repro steps? If I try simply the command above, I don't get touch request from yubikey, it simply gives the answer immediately, and I can't find how to enable touch policy?

$ ykman oath accounts code bla
bla  194431

OATH can require the touch or not. I don't know how did you create bla entry, but ykman oath accounts add has a -t switch to require touch. Also in the official GUI app it can be enabled/disabled per code/service.

After creating an entry that require touch, I have:

~ ❯ ykman oath accounts code twitch
Touch your YubiKey...

Gotcha, -t is exactly what I missed, many thanks, I can reproduce this now, we should definitely try to support this 👍 If you or anyone else want to give it a go, let me know here in the ticket, we can try to research something together and find a way forward.

I'm sorry, but I'm just and end-user with zero knowledge of Go. I can contribute with extensive testing, but unfortunately you can't rely on me in terms of actual coding.

maximbaz commented 2 years ago

That's completely fine, ideas and testing, your helpful repro steps, are all also very valuable 👍

@ftpd could you please confirm how you use this feature in your every day life? Do you just type ykman oauth command in terminal / have some shortcut for it? Or is there a GUI app that can retrieve the key? The reason I'm asking is because a quick and dirty solution to this request could simply be an infinite loop that checks if ykman oauth ... command is running for longer than 1 or 2 seconds - if it is, it means Yubikey is waiting for a touch. We use something similar for one of the other methods today. But this won't work directly if there are multiple ways to get the code, not only ykman oauth.

My main usage is: every morning when I run aws-vault for the first time this day (I'm a DevOps), I have to enter an OTP code. This is my main use case, I have a keyboard shortcut to run a simple scripts containing ykman oath account code work-aws and put the result into the clipboard.

There is indeed also a gui: https://www.yubico.com/products/yubico-authenticator/ and I use it from time to time when I'm logging into a website requiring TOTP code - but I won't say I do it often and I think no one does.

For a quick workaround I can of course create a notification with notify-send when I start my script - but it would be nice to have it in the detector, so each time I retrieve a code (whatever if in GUI or from a CLI script) I get a notification. Let's say it's just consistent ;-)
