Challenges I ran into
One specific problem for this application was the storage of JWT tokens on the frontend. JWT tokens are generated on the backend. Cookies or session storage are vulnerable to fisching attacks on the frontend.
Thus, to safely use a jwt token, I created a read-only cookie and saved my token there. I called it access token.
The problem with a read-only token is that it also cannot be accessed by the user.
So another jwt token is created called refresh token every 15 minutes upon verifying the access token which is then used for all the api calls.
The benefit of using it is that even if a hacker gets hold of refresh token, he can only access the account for 15 minutes. The access token is safe as it is a read-only cookie.
