title: express.js phone number authentication
body: <p>I want to implement authentication in my <code>express.js</code> api with phone number, like whatsapp or telegram. I have experience with <code>passport.js</code> but i have not found any strategy for phone numbers.</p>
  
  <p>My aproach is that if i get a phone number by a post request i generate an ID which i send to the specific phone number by sms. If i get back the ID and phone number pair in post request i authenticate the session. Is my aproach good? Is there any npm package which could be useful for me?</p>
