Can I disable 3 digit challenge code in WebCrypt App?
Like the settings in the OnlyKey app for the OnlyKey SSH/GPG agent: `Setting Derived Key User Input Mode` or `Setting Stored Key User Input Mode` to `Button Press Required`.
I’ve tried the WebApp several times. I am always too slow to enter the 3 numbers in 10 seconds. 🥴

Yes you can change derived challenge mode in the app preferences this works for webapp and agent.

Damn, am I too stupid? Have changed several times to `Button Press Required` (I tried in Config Mode on the 1st and 2nd profile)
But I always have to enter the 3 numbers in the web app.
App v5.3.1 on Debian 8, 9 & 10 - OnlyKey Firmware v2.1.0-prod from [OnlyKey Standard Edition firmware](https://docs.crp.to/upgradeguide.html)
The worst is: OnlyKey is sold out at [Amazon.de](http://Amazon.de). ☹

Once set to Button Press Required you will notice that after pressing any button the OnlyKey works with webcrypt. An alternative to [Amazon.de](http://Amazon.de) is to purchase OnlyKey from [https://onlykey.io](https://onlykey.io)

Oh man, I’ve got it. 🤦♂️ Even if you have switched to `Button Press Required`, a text like
> You have 10 seconds to enter challenge code 4,5,1 on OnlyKey.
appears in the web app. So it worked the whole time and I got confused by the message.
😋 I wanted to order in the [onlykey.io](http://onlykey.io) shop when I saw [Amazon.de](http://Amazon.de) is empty. But Coinbase Commerce didn’t work for non-US customers.
It has just now working again and I ordered 2 pieces. I hope they will be here in Germany in 2-3 weeks.
_lesson learned: Don’t give away **yours** OnlyKey’s to friends and family._ 🙃

The two keys were here in 6 days from the USA to Germany. 🕶 Impressively fast in the Corona period.
_And cheap if you got into cryptocurrency at the right time._ 🤑
