This RoundCube plugin adds the 2-step verification(OTP) to the login proccess.
It works with all TOTP applications RFC 6238

Also thx to Victor R. Rodriguez Dominguez for some ideas and support
- Clone from github: HOME_RC/plugins$ git clone https://github.com/alexandregz/twofactor_gauthenticator.git
(Or use composer HOME_RC$ composer require alexandregz/twofactor_gauthenticator:dev-master
NOTE: Answer N when composer ask you about plugin activation)
- Activate the plugin into HOME_RC/config/config.inc.php: $config['plugins'] = array('twofactor_gauthenticator');
Go to the Settings task and in the "2steps Google verification" menu, click 'Setup all fields (needs Save)'.
The plugin automatically creates the secret for you.
To add accounts to the app, you can use the QR-Code (easy-way) or type the secret. After checking the first code click 'Save'.
Also, you can add "Recovery codes" for use one time (they delete when are used). Recovery codes are OPTIONAL, so they can be left blank.
If config value force_enrollment_users is true, ALL users needs to login with 2-step method. They receive alert message about that, and they can't skip without save configuration
If config value 2step_codes_on_login_form is true, 2-step codes (and recovery) must be sended with password value, append to this, from the login screen: "Normal" codes just following password (passswordCODE), recovery codes after two pipes (passsword||RECOVERYCODE)
Actually only into samefield branch
Codes have a 2*30 seconds clock tolerance, like by default with Google app (Maybe editable in future versions)

Tested with RoundCube 0.9.5 and Google app. Also with Roundcube 1.0.4
Remember, sync time it's essential for TOTP: "For this to work, the clocks of the user's device and the server need to be roughly synchronized (the server will typically accept one-time passwords generated from timestamps that differ by ±1 from the client's timestamp)" (from http://en.wikipedia.org/wiki/Time-based_One-time_Password_Algorithm)

To log errors with bad codes, change the $_enable_logs variable to true.
The logs are stored to the file HOME_RC/logs/log_errors_2FA.txt -directory must be created
You can define whitelist IPs into config file (see config.inc.php.dist) to automatic login -the plugin don't ask you for code
To deactivate the plugin, you can use two methods:
To only one user: restore the user prefs from DB to null (rouncubeDB.users.prefs) -the user plugin options stored there.
To all: remove the plugin from config.inc.php/remove the plugin itself
