OAuth2 BFF for SPAs — Stop Putting Tokens in localStorage

1. 1Implement OAuth2 BFF pattern in your SPA to handle authentication
2. 2Use a backend-for-frontend (BFF) server to store and manage access tokens
3. 3Configure your BFF server to handle token refresh and revocation
4. 4Test your implementation for security vulnerabilities and XSS exploits
5. 5Apply additional security measures such as Content Security Policy (CSP) and HTTP-only cookies

Frontend developers and security engineers can benefit from this approach to protect user data and prevent XSS exploits

💡 Storing access tokens in localStorage makes your SPA vulnerable to XSS exploits, use OAuth2 BFF instead
