 ## Authentication
 
-The DAX API supports the user name and password authentication method.
+The DAX API supports [Kerberos][ref-kerberos] and [NTLM][ref-ntlm] authentication
+methods.
 
-## Using DAX API with Power BI
+While NTLM can be used for testing purposes, we strongly recommend configuring
+Kerberos for production environments.
+
+## Data modeling
 
 <InfoBox>
 
-The DAX API works only with [views][ref-views], not cubes.

-### Connection methods
-
-Power BI provides [three methods][link-powerbi-connection] to connect to data
-sources: _live connection_, _DirectQuery_, and _import mode_.

-| | Live connection | DirectQuery | <nobr>Import mode</nobr> |
-| --- | --- | --- | --- |
-| Data location | 🟢 Data source | 🟢 Data source | 🟡 Power BI |
-| Data freshness | 🟢 Real-time data | 🟢 Real-time data | 🟡 Stale copy |
-| Semantic model | <nobr>🟢 Up-to-date model</nobr> | 🟡 Stale copy | 🟡 Stale copy |

-
-__It's recommended to use a _live connection_ whenever possible.__ Use _DirectQuery_
-if you need to write your own DAX queries, but be aware that you must manually
-synchronize semantic models as they evolve. _Import mode_ is not recommended, as
-it removes the benefits of using a semantic layer.
