# Common Questions and Answers

## Can I sign in with Google?

Yes you can! Pass the flag `-a google` (replacing `-a ptc`) to use Google authentication.

If you happen to have 2-step verification enabled for your Google account you will need to supply an [app password](https://support.google.com/accounts/answer/185833?hl=en) for your password instead of your normal login password.


## ...expected one argument.

The -dp, -dg -dl, -i, -o and -ar parameters are no longer needed. Remove them from your query.

Your OS is missing the `gcc` compiler library. For Debian, run `apt-get install build-essentials`. For Red Hat, run `yum groupinstall 'Development Tools'`
