Assuming you have setup the 5Ci according to the instructions by Yubikey, and that you are a Premium Bitwarden customer, you might find this helpful if you haven’t already seen it:

5Ci and Neo as USB Keyboard ARE supported but the instruction screen in the app has some problems.

- Latest Bitwarden App
- "One of my keys supports … NFC" is unchecked in the YubiKey OTP section.
When the Bitwarden iPhone app asks for your YubiKey it appears that it was originally designed for the YubiKey NEO with NFC. It should be updated to include wording for, and activation by, the YubiKey 5Ci via the lightning port.
**First, the wording**:
> To continue, hold your YubiKey NEO against the back of the device.
Now that you can also use the YubiKey 5Ci via the lightning port, this wording should be changed to something generic or to include the YubiKey 5Ci and how to activate it (Currently: Plug YubiKey into lightning port, tap Cancel, tap the text field, and then press buttons on side of YubiKey).
**Second, the text field**:
The way the current Bitwarden app works, to use the 5Ci you must first tap Cancel to stop the "Ready to Scan" popup window and then tap the (black on black background) text field immediately above the "Remember me" area. That text field is not at all obvious or intuitive, as you can see from Screenshot 2 below. At the very least, making that text field contrast against the black background might be necessary.
Ideally though, the whole process/popup should be changed from "Ready to Scan" to "Waiting for YubiKey", and to handle input from the 5Ci via lightning port (and USB-C for Android?) the same way it does for the NEO via NFC by automatically selecting the text field/placing the resulting key into the text field.
Thanks!

If I connect a Yubikey 4c to an iPad Pro (2018) via the native USB-C port and to… uch the button in any text entry field, the expected OTP string is entered. However, at the `Yubikey Security Key` page of the login flow, the help text and image describes usage for an NFC Yubikey and there is no user discoverable corresponding text entry field to recover the string.
**EDIT:**
The horizontal rule on the login page is a text entry field masquerading as a horizontal rule. Tapping in the right place above it will focus the text entry and allow a Yubikey 4c to work. Would it be possible to auto-focus the field on moving to this screen in the flow, use a more obvious text field outline, or similar?
Thanks for considering!
