An entry control method conducted by a computer of an entry system which controls an opening/closing operation of a door of a moving body, the method comprising:

• an acquisition step of repeatedly acquiring a face image of a target person approaching the moving body from a camera provided in the moving body;
• an authentication step of authenticating that the target person is a registered user based on the face image;
• and
• a control step of automatically opening the door of the moving body when the authentication is a success in the authentication step,
• wherein in the authentication step, a notice indicating whether or not the authentication is a success is output from an output device provided in the moving body to outside of the moving body every time the authentication is executed, and
• in the control step, when the authentication becomes a success after the authentication becomes a failure for a predetermined prescribed number of times in the authentication step, a mode of movement of the door at the time of automatically opening the door is made different from a mode when the authentication becomes a success with the number of times less than the prescribed number of times in the authentication step.
