Module sso 

Garmin SSO Authentication

Implements the Garmin Connect SSO login flow using the mobile JSON API.

Background

The previous implementation scraped <title> tags from Garmin’s SSO HTML page to determine login status (matching garth < 0.8.0). Garmin changed their SSO page structure, breaking this approach.

This implementation ports the approach from garth 0.8.0, which switched to Garmin’s mobile JSON API endpoints:

• GET /mobile/sso/en/sign-in — establish session cookies
• POST /mobile/api/login — submit credentials, receive ticket or MFA challenge
• POST /mobile/api/mfa/verifyCode — verify MFA code if required
