var otv = require('one-time-value')

// Basic usage
var value = otv(generator)
var val = value('key')
value.verify('key', val) // true
value.verify('key', val) // false

function generator () {
  return Math.random()
    .toString(32)
    .substr(2)
}

// With TTL (in milliseconds)
var value = otv(generator, 1000)
var val = value('key')

value.expiry('key') // timestamp

setTimeout(function () {
