A television (password entry apparatus) creates and stores a table for selection and entry of a password character. The table includes: a password character matrix in which characters that make up a password (hereinafter referred to as "password characters") are arranged in M rows and N columns; M numbers of row heading information in the rows of the matrix; and N numbers of column heading information in the columns of the matrix. The row heading information and the column heading information in the table are randomly created. When a user selects and enters row heading information and column heading information by using a remote control, a password character that corresponds to the row heading information and the column heading information selected and entered by the user is input into the television.
