It is possible to setup Access Manager to provide users with different authentication processes. The following example is for Password Reset but you can use this for any authentication process that you wish. To do this login as the admin and go to the Authentication page and select the Password Reset entry. In the list to the right of the authentication flow you should see an option at the bottom named Scheme Selection, this module will allow users to select which authentication process, that you have configured, they will use to progress their login. 
We'll add only the Scheme Selection module and remove the existing modules so that user's must choose their login process before they can begin. Now save the scheme.
Now you will need to create the processes that the users can use, ensure that Password Reset is still selected and now press the Add button that is next to the dropdown for the Scheme option. You will be prompted to set a name, this is what will be displayed on the option the user selected, so lets name this "Forgot my password - reset via questions"
A new scheme is created and will displayed, it begins empty so as the user has provided no information up to this point we will require both their username and answers, so add the Username module and the Reset Questions modules then save
Repeat this process to add additional schemes and assign the modules you require for that login option, when the user now selects the Forgot my Password option they will be presented with all options that you've configured.
