"What is Auth0 and why use it for React authentication?"

"Auth0 is an identity and access management platform that provides secure authentication, authorization, and user management. It's ideal for React apps because it offers pre-built components, handles security best practices, supports multiple authentication methods, and provides token management out of the box."

"How do you check if Auth0 tokens are expired in React?"

"Check token expiration by comparing the current time with the token's 'exp' claim. Use the Auth0 SDK's isAuthenticated() method, manually decode the JWT to check expiration, or implement automatic token refresh with the getTokenSilently() method."

"What happens when Auth0 tokens expire?"

"When Auth0 tokens expire, API requests will fail with 401 Unauthorized responses. The application should detect this, redirect users to login, or automatically refresh tokens using refresh tokens if available and properly configured."

"How do you implement automatic token refresh in React with Auth0?"

"Implement automatic token refresh using Auth0's getTokenSilently() method within a useEffect hook or HTTP interceptor. This method checks token expiration and silently refreshes tokens without requiring user interaction, maintaining seamless user experience."

"What are best practices for Auth0 token security in React?"

"Best practices include storing tokens securely (avoid localStorage for sensitive tokens), implementing proper token expiration checks, using HTTPS, enabling token rotation, implementing logout functionality that clears all tokens, and validating tokens on the server side."
