FieldMasked

FieldMasked

is an option to InputField that determines whether to mask user input.

Details

  • An option setting FieldMasked->True specifies that the contents of an input field should be masked.
  • Masked input fields are typically used for input fields that hold private information such as passwords.
  • Input fields are masked visually and from attempts to copy the contents to the clipboard.
  • A masked input field displays exactly one asterisk for each character in the input field.

Examples

Basic Examples  (1)

Create a masked input field:

Wolfram Language code: InputField["abcdefg", String, FieldMasked -> True]

Scope  (1)

Typesetting constructs are not masked, but individual characters are:

Wolfram Language code: InputField[Sqrt[4321 / 8765], FieldMasked -> True]

Possible Issues  (1)

Although text is masked, it is not encrypted and can be accessed programmatically:

Wolfram Language code: InputField["This is a secret", String, FieldMasked -> True] SelectionMove[EvaluationNotebook[], Previous, Cell]; NotebookRead[EvaluationNotebook[]][[1, 1, 1, 1, 1, 2]]
