Getting started with the .NET MAUI Toolkit OTP Input control
Let’s explore how to integrate the .NET MAUI Toolkit OTP Input control into your app.
Step 1: Create a .NET MAUI project
Start by creating a .NET MAUI project.
Step 2: Add the Syncfusion® .NET MAUI Toolkit Package
Syncfusion® .NET MAUI Toolkit controls are available on the NuGet Gallery. In Visual Studio, access the NuGet package manager, search for Syncfusion.Maui.Toolkit and then install it.
Step 3: Register the handler

public static class MauiProgram
{
public static MauiApp CreateMauiApp()
{
var builder = MauiApp.CreateBuilder();
builder
.ConfigureSyncfusionToolkit()
.UseMauiApp<App>()
.ConfigureFonts(fonts =>
{
fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
});
return builder.Build();
}
}
Step 4: Add the namespace
Now, add the Syncfusion.Maui.Toolkit.OtpInput namespace in your XAML page.
xmlns:otpInput="clr-namespace:Syncfusion.Maui.Toolkit.OtpInput;assembly=Syncfusion.Maui.Toolkit"
