How to create Password Checklist in ReactJS ?

The password checklist in the React JS app is a list of password validation steps or conditions that should be fulfilled. These conditions are automatically checked when the password is input in the input field.

Prerequisites:

• React JS

Approach too create Password Checklist:

To add our checklist we are going to use the react-password-checklist package. The react-password-checklist package helps us to integrate the password checklist into our app. So first, we will install the react-password-checklist package and then we will add a checklist on our homepage.

npx create-react-app gfg
