title: Firebase Authentication connect Email with Phone
body: <p>I am currently using <strong>Email</strong> and <strong>Phone number</strong> authentication using Firebase.</p>
  
  <p>And i have <strong>3</strong> EditText for:</p>
  
  <ul>
  <li>Email</li>
  <li>Phone Number</li>
  <li>Password</li>
  </ul>
  
  <p>But the problem is when the user is done registering it obviously creates <strong>2</strong> instance of accounts, one for the <strong>Email</strong> and second for the <strong>Phone number</strong>.</p>
  
  <p>I would like to link the <strong>Email</strong> and <strong>Phone number</strong> together as one account. Is there any way to do that?</p>
