Abstract
A password recovery method, system, cloud server and electronic device. The method includes: a cloud server receives a login password recovery request for a device sent by a cloud service client which carries a device serial number and an encryption challenge string; wherein, the encryption challenge string is encrypted by a password recovery verification code randomly generated by the device; the cloud server determines whether the device serial number is bound to a cloud service account of the cloud service client, and the encryption challenge string is sent to a password server when it is determined that the device serial number is bound to a cloud service account of the cloud service client; the cloud server receives the password recovery verification code decrypted from the encryption challenge string returned by the password server, and sends the password recovery verification code to the cloud service client, so that the cloud service client can display the password recovery verification code to the user. The embodiments of the present application improve the convenience and reliability of the device login password recovery.
