Back in your Infisical instance, make sure to set the following environment variables:

- `CLIENT_ID_GOOGLE_LOGIN`: The **Client ID** of your GCP OAuth2 application.
- `CLIENT_SECRET_GOOGLE_LOGIN`: The **Client Secret** of your GCP OAuth2 application.
- `AUTH_SECRET`: A secret key used for signing and verifying JWT. This can be a random 32-byte base64 string generated with `openssl rand -base64 32`.
- `SITE_URL`: The URL of your self-hosted instance of Infisical - should be an absolute URL including the protocol (e.g. https://app.infisical.com)
  
Once added, restart your Infisical instance and log in with Google

FAQ

<AccordionGroup> <Accordion title="Why is Google SSO not working?"> It is likely that you have misconfigured your self-hosted instance of Infisical. You should:

- Check that you have set the `CLIENT_ID_GOOGLE_LOGIN`, `CLIENT_SECRET_GOOGLE_LOGIN`, 
`AUTH_SECRET`, and `SITE_URL` environment variables.
- Check that the **Authorized redirect URI** specified in GCP matches the `SITE_URL` environment variable.
For example, if the former is `https://app.infisical.com/api/v1/sso/google` then the latter should be `https://app.infisical.com`.
