Session Cookies vs. Tokens: Key Differences Explained
Understanding the contrast between session cookies and access tokens is critical for engineers building secure web applications . Session cookies are typically kept on a user's browser and terminate when the session is ended , fulfilling as a mechanism to track a client's state across several pages . In contrast , tokens are cryptographic values that can be kept on the backend and signify a visitor's identity status, offering greater security and the ability to scale your system more easily .
