Dynamic Business Central 365: ExtendedDatatype – Part 2: Masked

In Part 1, we explored the contact-related datatypes —  PhoneNo, URL, and  EMail  that make Business Central pages more interactive.

In this post, we’ll focus on the Masked ExtendedDatatype, which plays a vital role in privacy and data protection within Microsoft Dynamics 365 Business Central.

Masked — Protect Sensitive Information

The Masked ExtendedDatatype allows you to hide the actual text value of a field on the page by displaying it as dots (••••).
This ensures that sensitive data — such as passwords, tokens, API keys, or confidential IDs — remains visible only to authorized users who can view or edit the field.

Unlike field-level security or permissions, Masked is purely a UI-level protection — it affects only how the value is displayed, not how it’s stored in the database.

The field behaves like a normal text field, but the displayed value appears as dots (••••).
