Abstract
One example method includes a device management system detecting an attempt to access a user account by an unenrolled device. The device management system identifies a first enrolled device of the user account by accessing a signature chain of the user account. The device management system facilitates a transmission of a cryptographically-signed enrollment request from the unenrolled device to the first enrolled device. The first enrolled device is configured to cryptographically validate the enrollment request. The first enrolled device is further configured to generate an encrypted attestation message that indicates that the unenrolled device has been authenticated. The unenrolled device can receive and decrypt the encrypted attestation message based on a passcode being displayed on the first enrolled device. The device management system receives a decrypted attestation message from the unenrolled device and updates the signature chain to include a new sequential record for the unenrolled device.
