Authentication & Account Management
Authentication & Account Management Skill
This skill defines mandatory standards for implementing secure, production-grade authentication in Antigravity projects. All implementations MUST follow Google's OAuth 2.0 best practices.
1. Core Principles
| Principle | Requirement |
|---|---|
| SSO First | Prefer Google OAuth 2.0 over custom credentials |
| Least Privilege | Request only the minimum scopes required |
| Defense in Depth | Validate on both client and server |
| Secure by Default | All protected routes require authentication |
2. Google OAuth 2.0 Best Practices (MANDATORY)
