How to Hide/Show Password with Custom Tkinter

When developing applications that require user authentication, one common feature is the ability to hide or show the password input. Although it seems like a simple task, users sometimes struggle to figure out how to implement this with Custom Tkinter. Fortunately, with the right approach, toggling the visibility of passwords in your Tkinter applications can be straightforward. In this post, we will guide you through the process of achieving this functionality.

Understanding the Problem

With typical Entry widgets in Tkinter, you can easily configure them to obscure the input text, making them suitable for password fields. However, when working with the CtkEntry widget provided by CustomTkinter, you might find that the show option is not directly available on it. Instead, you need to dig a little deeper to manipulate its underlying Entry section for your purpose.

The Solution: Step-by-Step

Let’s get started with the solution to toggle password visibility in a Custom Tkinter application.

Step 1: Import Necessary Libraries

Make sure you import both tkinter and customtkinter at the beginning of your script.

Step 2: Create the Toggle Function

You need to create a function that will handle the toggling of password visibility. This function will check if the show property of the internal Entry widget is currently set to an empty string (indicating that the password is visible). If it is, we will set it to '*' to obscure the password. Otherwise, we will make it visible again by setting it back to an empty string.

Here’s how you can implement the toggle logic:

Step 4: Add the Password Entry Field

Now, you’ll need to add the CtkEntry widget where users will input their passwords.

Step 5: Create the Toggle Button

Finally, you need to create a button that users can click to show or hide their password. Connect this button to the toggle_password function.
