How to add a password strength indicator in Bubble.io: Step-by-Step Guide

Adding a Password Strength Indicator in Bubble.io

 

Adding a password strength indicator to your Bubble.io application is a great way to enhance user experience and security by providing immediate feedback on the strength of passwords being created by users. This guide will walk you through the entire process step-by-step.

 

Prerequisites

 

• A Bubble.io account with a project where you want to add the password strength indicator.
• Understanding of Bubble.io, including creating workflows and UI elements like inputs and text elements.
• Some basic knowledge of using regular expressions might be helpful but not necessary.

 

Understanding Password Strength Indicators

 

• A password strength indicator evaluates the strength of a password based on its length, complexity, and variety of character types used.
• Common checks often include evaluating the presence of uppercase letters, lowercase letters, numbers, and special characters.

 

Setting Up Your Bubble.io Environment

 

• Open your Bubble.io project where you wish to implement the password strength indicator.
• Navigating to your app's "Design" tab, set up the required UI elements.

 

Creating the Password Input and Strength Indicator Elements

 

• Add a Password Input Field: Drag and drop an Input element onto your page and set its Content format to "Password".
• Add a Text Element for Indicator: Place a Text element next to or below the password input to serve as the indicator.

 

Implementing the Password Strength Logic

 

• Create States for Strength Levels:
  • Go to the "Data" tab and create custom states on the page to hold the strength assessment. Name them something like 'PasswordStrength'.
• Configure Workflows to Evaluate Password:
  • Set up a workflow that triggers when the input value changes.
  • In the workflow, use conditions to evaluate the password's content based on desired criteria (e.g., length, presence of numbers, etc.).
  • Use the "Set state of an element" action to update the PasswordStrength state based on these evaluations.
• Example of Evaluating Password:
  • Use regex patterns for checking conditions:

                Length Check: password:formatted as:number of characters >= 8
                Number Check: :extract with Regex([\d]) > 0
                Special Character Check: :extract with Regex([!@#$%^&\*]) > 0
                

• Adjust Text Element Based On Strength:
  • Use conditional formatting in the text element to display different messages or change the text color based on the strength level from your custom state.
  • Example conditions:
    • If PasswordStrength is low, text displays "Weak".
    • If PasswordStrength is medium, text displays "Medium".
    • If PasswordStrength is high, text displays "Strong".

 

Testing Your Password Strength Indicator

 

• Preview your application in Bubble.io and test various passwords in your input field.
• Ensure that the indicator updates in real-time and accurately assesses the password strength according to your configured rules.
• Test edge cases such as very short passwords, only numeric inputs, etc., to make sure your logic handles them appropriately.

 

Deploying Your Password Strength Indicator

 

• After thorough testing, deploy your app to send the password strength indicator live.
• Monitor user feedback and adjust your strength criteria or UI as needed for better user experience.

 

By following these steps, you can effectively integrate a password strength indicator into your Bubble.io project. This feature improves both the usability and security of your app, guiding users in creating strong, secure passwords.
