In case you want to pass a value for `${{ github.token }}`, you should pass `GITHUB_TOKEN` as secret: `act -s GITHUB_TOKEN=[insert token or leave blank for secure input]`.
## `GITHUB_TOKEN`
Github [automatically provides](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#about-the-github_token-secret) a `GITHUB_TOKEN` secret when running workflows inside Github.
If your workflow depends on this token, you need to create a [personal access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) and pass it to `act` as a secret:
```bash
act -s GITHUB_TOKEN=[insert token or leave blank for secure input]
```
**WARNING**: `GITHUB_TOKEN` will be logged in shell history if not inserted through secure input or (depending on your shell config) the command is prefixed with a whitespace.
