Copy the unzipped folder to your /lib/plugins directory and activate the plugin. Then, set your options in Admin → Configuration Settings. Don't forget to change the authentication type to authg2fa instead of authplain.
You can revert to authplain by editing your /conf/local.php file:
$conf['authtype'] = 'authplain';
Using the standard DokuWiki settings, users aren't able to change their DokuWiki passwords anymore. They will be always prompted with “Wrong Password”.
A DokuWiki setting can disable password verification on profile update:
$conf['profileconfirm'] = false;
The other problem is periodic rechecking of the user's credentials. By default, DokuWiki tries every 900 seconds to check the password. As there is no current 2FA secret available by that time, the check will fail and the user is logged out. You can increase the Timeout to, e.g. 24h, by settings:
$conf['auth_security_timeout'] = 24*3600;
The available settings are as follows:
The individual G2FA secrets can be configured in the user's profile and the QR Code displayed. An admin plugin is provided which allows the generation of new secrets. This is not yet feature complete.
The plugin is heavily based on authgoogl2fa, but extended by many features. Feel free to comment and request features below.

it would be nice if the user could test the just created/imported code to be sure that everything is ok. — Finkregh 2014-06-25 12:16
