The invention discloses an identity verification method and device. The identity verification method comprises the following steps: firstly, acquiring a first verification identifier bound with a first terminal identifier; then, acquiring a second user identifier bound with a first user identifier; acquiring a second verification identifier bound with a second user identifier; and lastly, judging whether the first verification identifier is the same as the second verification identifier or not by comparison in order to realize identity verification of the first user identifier. Through adoption of the identity verification method, the identity verification speed can be increased on the premise of ensuring user information and property safety, thereby increasing the network account login speed of a user.
