Abstract
In some implementations, encrypted data (e.g., application data, keychain data, stored passwords, etc.) stored on a mobile device can be accessed (e.g., decrypted, made available) based on the context of the mobile device. The context can include the current device state (e.g., locked, unlocked, after first unlock, etc.). The context can include the current device settings (e.g., passcode enabled/disabled). The context can include data that has been received by the mobile device (e.g., fingerprint scan, passcode entered, location information, encryption key received, time information).
