title: Firebase Password Validation allowed regex
body: <p>I was wondering if anyone knew the official allowed passwords for Firebase's Email and Password Authentication API.</p>
  
  <p>So far I understand that there is</p>
  
  <ul>
  <li>a minimum of 6 characters required</li>
  <li>a-z allowed</li>
  <li>A-Z allowed</li>
  <li>0-9 allowed</li>
  <li>special characters allowed ~`!@#$%^&amp;*()-_+=|}]{["':;?/>.&lt;,</li>
  <li>white spaces allowed</li>
  </ul>
  
  <p>If this is the case, would the regex for validation on my side just be <code>{6,}</code> ? (alternatively I could just check the length of the field)</p>
  
  <p>EDIT: I assume it's similar to <a href="https://support.google.com/a/answer/33386?hl=en" rel="noreferrer">Google's normal password requirements</a> but only requiring 6 characters instead of 8.</p>
