### Return type: [auth.Authorization](API_docs/types/auth_Authorization.md) or [account.Password](http://docs.madelineproto.xyz/API_docs/types/account_Password.html) or `['_' => 'account.needSignup']`
You must then use [complete2falogin](complete2FALogin.md) or [completeSignup](completeSignup.md) to login or signup, or simply start using `$MadelineProto` if the result is a `auth.Authorization` object.
$authorization = yield $MadelineProto->completeSignup(readline('Please enter your first name: '), readline('Please enter your last name (can be empty): '));
