How do I set up consent screens for third-party login?

To set up a consent screen for third-party login, you typically configure the app as an OAuth/OIDC client with the identity provider and define what user data/scopes you’re requesting. The exact steps depend on the provider, but the general process is the same.

Typical setup steps

1. Register your app with the identity provider

   • Create an application/client in the provider’s developer console.
   • Add your redirect/callback URL.
   • Get your client ID and client secret.

2. Configure OAuth/OpenID Connect scopes

   • Request only the data you need.
   • Common examples:
     • openid (required for OIDC login)
     • profile
     • email
   • If you need extra API access, add those scopes too.

3. Set up the consent screen details

   • App name
   • Logo
   • Support email
   • Privacy policy URL
   • Terms of service URL
   • Authorized domains, if required
   • Developer contact info

4. Define test users / publishing status

   • Many providers require you to choose between:
     • Testing mode: only approved/test users can log in
     • Production/public: any eligible user can consent
   • Some providers require verification if you request sensitive scopes.

5. Implement the login flow

   • Redirect users to the provider’s authorization endpoint.
   • Include your scopes and redirect URI.
   • After consent, exchange the authorization code for tokens.
   • Verify the ID token if using OpenID Connect.

6. Review privacy and verification requirements

   • If you request sensitive or restricted scopes, you may need:
     • App verification
     • Security assessment
     • Additional disclosures on the consent screen

Best practices

• Request the minimum scopes needed.
• Make the consent prompt clear and honest.
• Ensure your privacy policy explains what data you collect and why.
• Use HTTPS for redirect URIs.
• Validate tokens server-side.
