Multifactor Authentication (since 7.10.2)

Appsuite version 7.10.2 provides methods for users to require secondary, additional methods of authentication before creating a valid Appsuite session. These methods may include SMS messages, Time based authenticator methods, U2F compatible devices/keyfobs, and other custom methods.

Enabling Multifactor

The open-xchange-multifactor package is required for the core of multifactor authentication. For some methods (such as SMS), additional packages will be required.

With SMS, for example, you must also install a provider, such as open-xchange-sms-sipgate.

Then, multifactor must be enabled as a capability. This can be done in the file, or as a cascade value


Enabling SMS

First, the SMS provider must be installed and configured. Most will require a configured username and password, or AUTH_TOKEN. Install the needed package and configure.

At that point, you should enable SMS in the file


The following properties are also available

  • com.openexchange.multifactor.sms.tokenLength (default is 8 characters)
  • com.openexchange.multifactor.sms.tokenLifetime (Number of minutes until challenge expires)
  • com.openexchange.multifactor.maxTokenAmount (Maximum number of challenges before locked out)

Enabling TOTP

TOTP is Time-based One Time Password. This works with several apps available in mobile stores, such as Google Authenticator.

To enable, just set in the file


Enabling Backup String

This is a method to allow a user to log into their account if they lose their primary multifactor authentication device (say losing their phone or U2F token). It is a long string that they can copy, download, or print to use to unlock the account in the event of loss

To enable, set in the file


Enabling U2F

U2F is supported in Google Chrome, as well as Firefox (though requires user changing advanced settings).

In, enable U2F


Then, the domain that the user will be using must be specified. This will be used with the requests to the U2F device, and must mach the website. This configuration is config-cascade aware


Login Page

By default, the UI will change from the login page, draw the customized toolbar, then display a prompt for the multifactor authentication.

If you would prefer to have your login screen, or a different second factor screen used as the background, then you can configure in the as-config.yml

For example:

    host: all
    signinTheme: default
    multifactorBackground: pages/secondFactor
