Yubico Forum

Hello,
1 year agoa I bought a yubikey and I worked very well with it in my joomla sites..
today I try to do the same with a new joomla site installing the followwing com and plugins:
com_authyubikey-1.3
plugin_authyubikey-1.5
I deactivated the Authentication - Joomla plugin and put a user in the yubikey list.
after that I simply did the copy of the result of the https://upgrade.yubico.com/getapikey/ page:

Congratulations! Please find below your client identity and client API key.

Client ID: 4401
Secret key: kPC3Mk0u1i3T+kIa4Mm3UCmgcAY=

I copied the Client ID in the:
API ID (4401)
API Signature Key (kPC3Mk0u1i3T+kIa4Mm3UCmgcAY= )
(is this correct?..)

In the login form I write in the username the user name and in the password I write my password and yubikey finger generated OPT but when I try to login in my site I encounter the following problem:

Fatal error: Call to undefined function curl_multi_init() in C:\xampp\htdocs\J01\plugins\authentication\Yubico.php on line 302

Someone can help me?
thank you

That does not look to be a Yubico/Yubikey error, it looks to be an issue with one of the plugins that you recently installed. I would first check if you have cURL enabled on your php installation and also, what version of php are you using?
