    **2 Step Enrollment**
    
    Some tokens might need a 2 step initialization process like a smartphone 
    app. This way you can create a shared secret from a part generated by 
    the privacyIDEA server and from a second part generated by the smartphone 
    app/client.
    
    The first API call would be
    
       .. sourcecode:: http
       
           POST /token/init
           
           2stepinit=1
           
    The response would contain the otpkey generated by the server and the 
    serial number of the token. At this point, the token is deactivated and 
    marked as being in an enrollment state. The client 
    would also generated a component of the key and send his component to the 
    privacyIDEA server:
     
    The second API call would be
    
       .. sourcecode:: http
           
           POST /token/init
           
           serial=<serial from the previous response>
           otpkey=<key part generated by the client>
    
    Each tokenclass can define its own way to generate the secret key by 
    overwriting the method ``generate_symmetric_key``. The
    Base Tokenclass contains an extremely simple way by concatenating the 
    two parts. See
    :func:`~privacyidea.lib.tokenclass.TokenClass.generate_symmetric_key`

    **2 Step Enrollment**
    
    Some tokens might need a 2 step initialization process like a smartphone 
    app. This way you can create a shared secret from a part generated by 
    the privacyIDEA server and from a second part generated by the smartphone 
    app/client.
    
    The first API call would be
    
       .. sourcecode:: http
       
           POST /token/init
           
           2stepinit=1
           
    The response would contain the otpkey generated by the server and the 
    serial number of the token. At this point, the token is deactivated and 
    marked as being in an enrollment state. The client 
    would also generated a component of the key and send his component to the 
    privacyIDEA server:
     
    The second API call would be
    
       .. sourcecode:: http
           
           POST /token/init
           
           serial=<serial from the previous response>
           otpkey=<key part generated by the client>
    
    Each tokenclass can define its own way to generate the secret key by 
    overwriting the method ``generate_symmetric_key``. The
    Base Tokenclass contains an extremely simple way by concatenating the 
    two parts. See
    :func:`~privacyidea.lib.tokenclass.TokenClass.generate_symmetric_key`
