Overview
Affected versions of this package are vulnerable to Brute Force due to the excessive login attempt mitigation in place in FirstFactorPOST() allowing two different authentication methods to be used by the same requester, thereby effectively doubling the attempt lmiit.

Workaround
This vulnerability can be negated by disabling one of the two authentication methods.
