Hey everyone,
I’m working on an app that lets users connect their Facebook accounts. I’m wondering if it’s safe to send the Facebook access token from the frontend to the backend after the user connects.
Are there any security risks I should be aware of when doing this? I’m not sure if this is a good practice or if there are better ways to handle it.
If anyone has experience with this or knows about potential vulnerabilities, I’d really appreciate your input. Thanks in advance for any advice you can share!
hey echo, sending tokens client-side can be risky. have u thought about server-side auth flow? it’s generally safer. also, make sure to use short-lived tokens and refresh em regularly. dont forget to validate the token on ur backend too. good luck with ur project!
As someone who’s implemented Facebook authentication in several projects, I can share some insights. While transmitting access tokens from client to server isn’t inherently unsafe, it does present certain risks. I’ve found that implementing server-side OAuth flow provides better security. This approach keeps sensitive data on the server, reducing exposure.
Additionally, I always ensure to use HTTPS for all communications and implement proper token validation on the backend. It’s crucial to treat the access token as sensitive information and avoid storing it in local storage or cookies that could be vulnerable to XSS attacks.
In my experience, combining these practices with short-lived tokens and secure storage methods significantly enhances the overall security of the authentication process.
hmm, interesting question! have u considered using HTTPS for secure transmission? that might help protect the token. what about storing it in a secure cookie instead of sending directly? just brainstorming here. how are u handling user authentication overall? curious to hear more about ur setup!
