When you open Power Bi and try to connect to BI Connector through ODBC mode, in case if you're not prompted to enter username/password and received an error message as shown below, it may be because invalid credentials are stored in Power BI cache.

Step 1: Click on File menu which appears at the top left corner of Power BI page.
Step 2: Then, select Options and Settings and click on Data source settings from the menu.
Step 3: Choose the appropriate DSN name in Data source settings dialog.
Step 4: Click on Clear Permission button and click Delete.
Step 5: Post that you'll be taken to the dialog where you need to enter DSN credentials.
