1. A method of providing access to at least one password protected device via a password management system comprising a first password management server and a second password management server in data communication via a communication link, the method comprising:
determining, at the first password management server, an active password which is registerable as a device password with, and provides access to, the at least one password protected device, and at least one reserve password;
transmitting the active password and the at least one reserve password to the second password management server via the communication link, the active password for accessing the at least one password protected device from either or both first and second password management servers;
after communication of the active password and the at least one reserve password to the second password management server, determining, by the second password management server, that the communication link between the first password management server and the second password management server has failed;
updating, by the second password management server, the device password at the password protected device with one of the at least one reserve passwords;
determining, by the second password management server, that the communication link between the first password management server and the second password management server has been restored;
transmitting, by the second password management server, a notification of the update to the first password management server via the communication link; and
updating, by the first password management server, the active password at the second password management server to the one of the at least one reserve passwords based on the received notification.
