## ❊ Configure Yubikey Slot
In order for KeePassXC to properly detect your Yubikey, you must setup one of your two OTP slots to use a **Challenge Response****.**
Open Yubikey Manager, and select **Applications** -> **OTP**.
Next, select **Long Touch (Slot 2)**** -> ****Configure**
In the list of options, select **Challenge Response**.
You will then be asked to provide a **Secret Key**. You can either come up with your own, or click the **Generate** button if you wish to just use a random one.
At the bottom left is the option to **Require Touch**. Enabling this means that every time you save your database or open your database, your Yubikey will require that you touch it before it completes the action. This is optional.
Before you click **Finish**, ensure you write down the secret key you've generated. You must save that secret key if you want to set up multiple Yubikeys to open the same database. All Yubikeys must have the same challenge response programmed into Slot 2.
## ❊ Configure KeePassXC
Once you have **slot 2** on your Yubikey configured as a challenge response, open KeePassXC.
### New Database
If creating a new database, create the database as you normally would and continue to click **Next**.
When you get to the screen titled **Database Credentials**, click the button **Add Additional Protection** ...
Scroll down until you see the **Challenge Response** -> **Add Challenge Response**:
Scroll down to **Challenge Response** and you should see a dropdown box that lists your Yubikey. Make sure your Yubikey is plugged in.
If you do not see your Yubikey, press **Refresh**.
From this point, you can finish setting up your database.
### Existing Database
If you have an existing database you would like to add your Yubikey to, open your database with KeePassXC.
Once you are in, click **Database** at the top left, and select **Database Settings****.**
Once the dialog box opens, on the left side select **Security****.**
In the middle of the screen, click the button **Add Challenge-Response****.**
It should then load your Yubikey:
If your Yubikey does not appear in the list, ensure it's plugged all the way in, and press the **Refresh** button.
Once you see your Yubikey in the list, make sure it's selected.
After it is selected, you can press 
## ❊ Yubikey Touch
If you selected **Require Touch** when you first assigned a Challenge Response to slot 2 in the Yubikey Manager, you will be prompted with a notification each time you make a change to your KeePassXC database:
If you fail to touch your Yubikey within a certain number of seconds, your action will time out and changes will not be saved.
