This is an authentication module that allows applications to authenticate against the challenge response authentication mechanism (code available at https://github.com/pdvrieze/ProcessManager/tree/master/accountmgr). The library has a number of features:

• Uses public key cryptography to register a device specific key to the server
• Has its own permission request implementation to allow client apps to request permission to access the account through the intent mechanism, not through a notification (the default system activity causes permission errors).
