Design Pattern: Security – Masked Text

Aliases: Masking out

Context: In the user interface (UI) of a software system, the user enters protected information such as a password, an access key, a credit card number etc.

Problem: The entered information is visible during data entry and whenever any user (the one who entered the data, or a foreign user) opens the UI.


  • Information disclosure: sensitive data is visible in the UI.

Solution: Use the “Masked” field property to display dots instead of characters on the sensitive text field in the UI.
