hello,

Enable Two-Factor Authentication with YubiKey 5C NFC, show error:"The YubiKey value entered could not be validated successfully. Please try again."

I used last version WHMCS7.82, do you know this problem?

You have to sign up here first, https://upgrade.yubico.com/getapikey/

then enter the ID and secret key in WHMCS under SYSTEM SETTINGS > STAFF MANAGEMENT > TWO-FACTOR AUTH
