There are plenty of third party email clients that will work with gmail using OAuth2 instead of transmitting your username/password. Mail on Mac, Outlook, Thunderbird. What OS are you using?

Yes, I myself use Thunderbird portable, using IMAP (server imap.gmail.com) and ssl/tls for connection security, and OAuth2 as authentication method. Thank God it has worked well.
