A specific case of the Data query is the Password query, used for confidential information such as passwords or PINs. It uses the password editor, which functions much like any other editor, except that instead of the actual data, a dummy character (asterisk) represents each input character. In case of a numeric-only password, the asterisks appear as soon as characters are entered. In case of alphanumeric input, to support typing characters by repeated presses of the same numeric key, the character is displayed normally for a short time, and then changed into an asterisk.
For implementation information, see Queries.
