yes

**if commands stall, try removing and reconnecting your YubiKey**

Comment:
library and CLI tool (ykman) for configuring a YubiKey

Description:
The YubiKey Manager can configure FIDO2, OTP and PIV functionality on
a YubiKey. It works with any currently supported YubiKey. You can also
use the tool to check the type and firmware of a YubiKey. In addition,
you can use the extended settings to specify other features, such as to
configure 3-second long touch.

Install notice:
NOTE: yubikey-manager (ykman) is only partially functional on OpenBSD.

"ykman otp" is not functional as there is no suitable HID backend; some OTP
operations can be done with the old yubikey-personalization CLI tool and the
Qt-based yubikey-personalization-gui package.

For "ykman fido", make sure pcscd is running, and if commands stall,
try removing and reconnecting your YubiKey (likely to happen after each
command).
