Vuetify Confirm Password Validation Rule Tutorial:Vuetify is a popular framework for building attractive and responsive user interfaces in Vue.js applications. When creating forms, it's essential to validate user input, especially when dealing with sensitive information like passwords. This tutorial will guide you through setting up a Confirm Password validation rule in Vuetify text fields to ensure that users confirm their chosen password correctly.

Why Confirm Password Validation is Important?

Confirming a password during registration or when changing a password is a common practice to prevent mistakes and enhance security. By including this validation, you ensure that users enter the same password in both the "Password" and "Confirm Password" fields, reducing the risk of authentication issues and security breaches.

Implementing Confirm Password Validation in Vuetify

In this tutorial, we will create a simple registration form with two Vuetify text fields: one for the password and another for confirming the password. We'll set up custom validation rules for both fields to ensure they meet our requirements.

Here's the HTML structure of our form:

Vuetify Custom Validation for Confirm Password

<v-container>
    <h3>Vuetify set Confirm Password Validation Rule in text-fields</h3>
    <v-form @submit.prevent="register">
        <v-text-field label="Password" clearable v-model="password" type="password"
            :rules="passwordRules"></v-text-field>

        <v-text-field label="Confirm Password" clearable v-model="confirmPassword" type="password"
            :rules="confirmPasswordRules"></v-text-field>

        <v-btn type="submit" color="primary">Register</v-btn>
    </v-form>
</v-container>

Run

Next, let's dive into the JavaScript code for this form. We'll use Vue.js to handle data and validation:

In the JavaScript code, we define two computed properties: passwordRules and confirmPasswordRules. These properties return arrays of validation functions. For the "Password" field, we require it to be non-empty and at least 8 characters long. For the "Confirm Password" field, it must also be non-empty and match the "Password" field

Vuetify: Confirm Password Validation Rule for Text Fields

<script>
    new Vue({
        el: '#app',
        vuetify: new Vuetify(),
        data() {
            return {
                password: "",
                confirmPassword: "",
            };
        },
        methods: {
            register() {
                // Perform registration logic here
            },
        },
        computed: {
            passwordRules() {
                return [
                    (v) => !!v || "Password is required",
                    (v) => v && v.length >= 8 || "Password must be at least 8 characters",
                ];
            },
            confirmPasswordRules() {
                return [
                    (v) => !!v || "Confirm Password is required",
                    (v) => v === this.password || "Passwords do not match",
                ];
            },
        },
    });
</script>
