Checks authentication code. Works only when authGetState returns authStateWaitCode. Returns authStateWaitPassword or authStateOk on success
### Params:
| Name | Type | Required | Description |
|----------|:-------------:|:--------:|------------:|
|code|[string](../types/string.md) | Yes|Verification code from SMS, Telegram message, voice call or flash call|
|first\_name|[string](../types/string.md) | Yes|User first name, if user is yet not registered, 1-255 characters|
|last\_name|[string](../types/string.md) | Yes|Optional user last name, if user is yet not registered, 0-255 characters|
### Return type: [AuthState](../types/AuthState.md)
### Example:
```
$MadelineProto = new \danog\MadelineProto\API();
if (isset($token)) { // Login as a bot
$MadelineProto->bot_login($token);
}
if (isset($number)) { // Login as a user
$sentCode = $MadelineProto->phone_login($number);
echo 'Enter the code you received: ';
$code = '';
for ($x = 0; $x < $sentCode['type']['length']; $x++) {
$code .= fgetc(STDIN);
}
$MadelineProto->complete_phone_login($code);
}
$AuthState = $MadelineProto->checkAuthCode(['code' => string, 'first_name' => string, 'last_name' => string, ]);
```
Or, if you're into Lua:
```
AuthState = checkAuthCode({code=string, first_name=string, last_name=string, })
```
