How can I avoid frequent re-authentication when using Google Cloud Platform (GCP) (e.g., auto-renew, increase token expiry, another auth method)?

I use Google Cloud Platform (GCP) to access the Vertex AI API. I run:

```
gcloud auth application-default login --no-launch-browser
```

to get an authorization code:

However, it expires after 1 or 2 hours, so I need to re-authenticate constantly. How can I avoid that? E.g., increase the expiry time, authenticate automatically, or authenticate differently in such a way I don't need an authorization code.
