Abstract
Mobile device key management is disclosed. A master key is secured using a password-based key to generate a first encryption information. The password-based key is generated based at least in part on a password associated with a mobile device. The master key is also secured using an unlock key to generate a second encryption information. The unlock key is stored at a server, and in certain cases is not stored on the mobile device. The first encryption information and the second encryption information are stored on the mobile device. The mobile device is configured to extract the master key from the first encryption information using the password. In the event that the master key is not extracted using the password, the mobile device is configured to extract the master key from the second encryption information using the unlock key received from the server.
