Hello,
I've been trying to add the OPT token from accounts.fedoraproject.org to my
yubikey. I get a QR code and a otpauth://totp/username?secret=xxx URI.
I copypasted the xxx secret (56 characters: digits and uppercase letters)
and tried to add it via YubiKey Manager GUI via Applications/OTP as
OATH-HOTP (6 digits).
I get "Failed to configure Long Touch (Slot 2). undefined" error.
When I tried to use the CLI:
$ ykman otp hotp -d 6 -c 0 2 xxx
I get "Error: key lengths >20 bytes not supported".
Is there a way to use YubiKey for accounts.fedoraproject.org OTP, or is the
device not compatible?
You may want to check: https://github.com/fedora-infra/noggin/issues/202
Thanks. From that ticket I am not quite sure what the status actually is and
what are the next step. Should I post my failed experiment there?
My understanding: IPA supports yubikey HOTP, but noggin (the web
frontend) does not. So, it's not supported currently. You must use TOTP.
:(
I'll poke that ticket and see if we can move forward tho.
Indeed. With help from bachradsusi/plautrba on IRC, I was able to do:
$ ykman oath add -o TOTP -d 6 -t accounts.fedoraproject.org <secret>
And now I can do:
$ ykman oath code accounts.fedoraproject.org
Touch your YubiKey...
accounts.fedoraproject.org 123456
Which is nice, however originally I wanted to be able to just touch the device
to insert the code as if it was typed on my keyboard. That seems to work with
my another HOTP-token based auth, but not with Fedora's TOTP one.
So this seems to boil down to HOTP support in Noggin.
