// with symmetric key: (neccessarity to be considered!)
// 1. exchange symmetric key with server with AJAX request
// if no network yet, wait until user enter login
// upon receiving login request, exchange key with server
// 2. only with the key can the login info be parsed

// lifecycle -- session & mpw should be cleaned after browser exit

// without key:
// login page send mpw for background to initialize
