Hi,
This seems to be something controlled in Exchange, and may occur if the Integrated Windows Authentication has been enabled:
1). Open IIS management console.
2). Right click the "Exchange" virtual directory and select properties.
3). Select Directory Security tab; click Edit of "Authentication and access control".
4). Please check whether the "Integrated Windows Authentication" was checked.
5). If so, please uncheck it
6). Restart IIS admin service.
If the steps above doesn't help in your scenario, kindly refer to Exchange Forum to get more specific assistance:

If you simply want to OWA to prompt for credentials every time trying to login, please make sure that client machine has the IE security setting that requires to prompt for username and password. Let's take Internet Explorer 11 for example, go to
Internet Options -> Content -> AutoComplete
-> Settings -> Uncheck or check the User names and passwords on forms as you need ->
OK.
