MAUI Disable Soft keyboard for Entry

Option 1. Just use Label as @Sinatr said.

Option 2. Set the Entry IsEnabled=false:

Elements that are not enabled will not receive focus or respond to input events.

(In case you meant programmatically hide the keyboard once the Entry is focused)

Option 1. If you want to use platform-specific code, you can take a look at this SO answer

Option 2. If you want to use CommunityToolkit KeyboardExtensions:

YourPage.xaml

<Entry x:Name="Password"/>

YourPage.xaml.cs

using CommunityToolkit.Maui.Core.Platform;

Password.HideKeyboardAsync(CancellationToken.None);

EDIT: Your comment below is giving important context (you should include it on the original question). You are not looking for a way of programmatically hide your system keyboard or disable it (like you said on your original question). What you are really looking for is a way of changing Entry text input. Instead of the system keyboard, you want your barcode scanner.

The easiest way of achieving what you are looking for is to create a custom Entry and then apply a Hadler to keep the focus but not showing system keyboard:

public class BarcodeScannerEntry : Entry { }

Then on your MauiProgram.cs use this Handler:

    Microsoft.Maui.Handlers.EntryHandler.Mapper.AppendToMapping("BarcodeScannerEntryHandler", (handler, entry) =>
    {
        if(entry is BarcodeScannerEntry barcodeScannerEntry)
        {
#if ANDROID
            handler.PlatformView.ShowSoftInputOnFocus = false;
#endif
        }
    });

I have read from your comments that you are using "EDA51 or Zebra TC70". This you should put in your question because information like that is essential.

Android devices with physical keyboards are usually set up to not show their software keyboard when a numeric text field.

So the simple solution is to flag your password field to accept only numbers. I am using similar system to login in with a pin on datalogic/honeywell devices. But it should be the same on yours.

The suggested alternative for not showing keyboard on focus should work, but I know some hand held devices that will ignore this option, and display it anyway.

Also the suggested alternative for hiding the keyboard manually will work. There is timing issue if you try to hide it before it gets shown on focus, but it is technically 100% working solution. Also I like to use it with adjust pan option.

Use the inputmethodmanager from either the view or context

fun Context.hideKeyboard(view: View) {
    val inputMethodManager = getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
    inputMethodManager.hideSoftInputFromWindow(view.windowToken, 0)
}

fun View.hideKeyboard() {
    val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(windowToken, 0)
}
