The invention discloses an application verification code input method and device. The method comprises the steps of when it is determined that a position at which a current input point is located matches a verification code input position of an application, displaying at least one verification code in a candidate word selection box of an input method, wherein the verification code is obtained from a received short message; determining a first verification code matching the application from the candidate word selection box of the input method; and inputting the first verification code. According to the technical scheme, when the verification code needs to be input, at least the verification code is automatically displayed in the candidate word selection box of the input method, the first verification code matching the application is input from the candidate word selection box, in this way, a terminal user does not need to obtain the verification code from the short message and input the verification code, and the verification code input intelligence and efficiency are improved.
