What are the best practices for OAuth2 implicit flow?

The OAuth2 implicit flow is designed for client-side applications. Best practices include using short-lived access tokens, implementing state parameters to prevent CSRF attacks, and ensuring secure storage of tokens.

Why should I use short-lived access tokens?

Short-lived access tokens reduce the risk of token theft. If a token is compromised, it will only be valid for a short period, limiting potential damage.

What is a state parameter?

The state parameter is a value that you can include in the authorization request to maintain state between the request and callback. It helps prevent CSRF attacks by ensuring the response corresponds to the request.

How can I securely store tokens in a client-side application?

You can store tokens in memory or use secure storage options like sessionStorage. Avoid localStorage as it is more vulnerable to XSS attacks.
