Dynamics 365 Business Central: introducing the new MaskedType enum field-level property.
Business Central 2025 Wave 2 adds a MaskType enum property for table fields. Setting it to Concealed hides the field value in the UI until the user clicks an eye button to reveal it. This gives lightweight UI-only protection from casual observation, because the unmasked data still reaches the browser.

"The new property will be available starting from Dynamics 365 Business Central version 27.1 and it will not be enabled by default."
Key points
- MaskType enum property supports None (default, visible) and Concealed (hidden by default, revealed via eye button) values
- Supported on Code, Text, Decimal, and Integer fields only, and only on document and card pages, not on list page repeaters or grids
- Works on web client and mobile client; cannot be used together with ExtendedDatatype = Masked property
- Available starting from Dynamics 365 Business Central version 27.1 and requires enabling via Feature Management
- Provides UI-layer protection only; unmasked data is still transmitted to the web browser
Quotes
- “The new property will be available starting from Dynamics 365 Business Central version 27.1 and it will not be enabled by default.” (Critical implementation detail about when the feature becomes available and that it requires explicit enablement via Feature Management)
