You can add an optional title and prompt above the line of digits.
Use secure digit fields. Secure digit fields display asterisks instead of the entered digit onscreen. Always use a secure digit field when your app asks for sensitive data.
Clearly state the purpose of the digit entry view. Use a title and prompt that explains why someone needs to enter digits.
Not supported in iOS, iPadOS, macOS, visionOS, or watchOS.
