title: aiogram Why code has expired for different users with the same api_i and api_hash?
body: <p>I working on python telegram bot that allow login telegram client using registered user and then do some actions using user credentials ...
  ... But I got the following error:</p>
  <pre><code>ERROR: The confirmation code has expired (caused by SignInRequest)
  </code></pre>
  <p>I use the following libraries <code>aiogram</code> and <code>telethon</code>.
  The error above is provided by <code>telethon</code></p>
  <p>Looks like <code>telethon</code> cannot use the same <code>api_id</code> and <code>api_hash</code> for different users ...</p>
  <p>But if it is a case then I make bot useless, because user should now about <code>api_id</code> and <code>api_hash</code> and I cannot login telegram client by user credentials ... It is very strange ...</p>
  <p>Looks like it happens not for all accounts ... some accounts login successful ...</p>
  <p>Have anybody faced with the same error ?</p>
