You can't really use regex for this kind of validation because the characters could be in any order.

Instead, you should create a custom validation rule to perform each check on the input string:

import { Validator } from 'vee-validate'

Validator.extend('password', {
  getMessage: (field) =>
    'The ' + field + ' value must contain 1 uppercase, 1 lowercase, 1 number, and 1 special character.',
  validate: value => {
    return (
      /[A-Z]/.test(value) &&
      /[a-z]/.test(value) &&
      /\d/.test(value) &&
      /[!@#$%^&*()_\-+=`~<>?\\/;,.'"\][{}]/.test(value)
    )
  }
})

Usage:

<input v-validate="{ password: true }">

Can we take it as v-on:keypress="isPassword($event)" and write a method for it.

Technically possible, but isPassword() would just be checking the value of the input, which would essentially be duplicating the work of vee-validate. Why not use vee-validate?
