How to Create a Password Checklist With Next.js
In today’s world, online security is more important than ever. With so many online accounts to keep track of, it’s essential to have a strong and unique password for each one.
If you’re building a site, it’s even more important to ensure passwords are as secure as they can be. You can present a checklist to those using your site and ensure their password meets your requirements before you accept it.
Learn how to implement a password checklist using Next.js.
Why Use a Password Checklist?
There are many reasons why you might want to use a password checklist.
First, it can help you ensure that your users' passwords are strong and unique. By having a checklist of requirements, you can be sure that each password meets a certain standard.
Your users may not thank you for it, but you’ll be doing them a favor. By encouraging strong passwords, you’ll make it less likely that a hacker will gain access to one of your users' accounts.
Second, a password checklist can help to convey a sense of security. By publishing requirements, you’re telling your users that you take password security seriously.
You should be aware, however, that a password checklist is not a miracle solution to password problems. In fact, if you make your passwords too restrictive, it’s possible to make it easier for hackers to narrow down their options and brute-force a password. Ultimately, secure and unique passwords that usersstore in a password managerare best.
How to Create a Password Checklist
There are two ways to create a password checklist in Next.js. You can either use the in-built features or you can use an external module.
What You Will Need
To create a password checklist in Next.js, you will need the following:
Method 1: Using Built-In Features
Next.js comes with built-in features like hooks and context. There aredifferent types of hooksthat it’s possible to use to create a password checklist.
First, create a new file in your Next.js app and name itpasswordChecklist.js. In this file, you’re able to take password input from users, and you can check if the password meets the requirements.
In the above code, you first need to take password input from users. You can do this using theuseStatehook. This hook allows you to create a state variable and a function to update that variable. In this case, the state variable ispasswordand the function to update it issetPassword.
Next, you need to create a function to handle the form submission. This function will prevent the default action of the form (which is to submit the form) and it will check if the password meets the requirements.
The password requirements are that it must:
You can use theeverymethod to check if a password meets all the requirements. If it does, the password is valid. Otherwise, the code will display an error message.
Method 3: Using the react-password-checklist Module
Another way to create a password checklist in Next.js is by using thereact-password-checklistmodule. This module is easy to use, and it comes with a lot of features.
First, install the module using the following command:
Then, import the module in yourpasswordChecklist.jsfile:
This code passes the props minLength, specialChar, number, and capital to thePasswordChecklistcomponent. The component will use these props to check if the password meets the requirements.
You can also add translated messages to the component by passing themessagesprop. These strings override the default errors so you can use them for other languages or variations.
In the above code, themessagesprop stores alternative error messages. The component will display these messages when the password does not meet the requirements.
This method is more convenient because you don’t have to write the code to check if the password meets the requirements. There are also many other benefits of using this module such as:
Improve User Safety With a Password Checklist
A strong password is a key to online safety. It’s important to have a strong and unique password for each online account. By using a password checklist, you could be sure that each password meets a certain standard.
Your app users will also appreciate being able to see the password strength. This way, they can be sure that their passwords are strong enough. This will improve the user experience of your app and it will also improve the safety of your app users. Similarly, you can also validate the forms in your Next.js app.
Form validation is essential for a robust, secure web app. Thankfully, the Formik library can do much of the heavy lifting for you.
