=head1 NAME
Catalyst::Authentication::Credential::2FA - Authenticate a user
with a two-factor authentication code.
=head1 SYNOPSIS
use Catalyst qw/
Authentication
/;
package MyApp::Controller::Auth;
sub login : Local {
my ( $self, $c ) = @_;
$c->authenticate( { username => $c->req->param('username'),
password => $c->req->param('password') });
}
=head1 DESCRIPTION
This authentication credential checker takes authentication information
(most often a username), and only passes if a valid 2FA code is then
entered. It only works for Users that have an is_superuser flag set,
plus store the 2FA secret in a FixMyStreet::Role::Extra metadata key.
=head1 CONFIGURATION
# example
'Plugin::Authentication' => {
default => {
credential => {
class => 'MultiFactor',
factors => [
{
class => 'Password',
password_field => 'password',
password_type => 'self_check',
},
{
class => '2FA',
},
],
},
store => {
class => 'DBIx::Class',
user_model => 'DB::User',
},
},

=item class
The classname used for Credential. This is part of
L<Catalyst::Plugin::Authentication> and is the method by which
Catalyst::Authentication::Credential::2FA is loaded as the
credential validator. For this module to be used, this must be set to
'2FA'.
=back
=head1 USAGE
Once configured as indicated above, authenticating using this module is a
matter of calling $c->authenticate() as normal. If you wish to use it in
combination with e.g. password authentication as well (so it actually is
two-factor!), check out Catalyst::Authentication::Credential::MultiFactor.
