See firsthand why cookies are fundamentally insecure and how BrowserID provides a better solution
HTTP cookies have 5 fundamental security flaws that make them unsuitable for modern web applications
Cookies are stored in SQLite databases with minimal encryption. Any process with file system access can read them.
Impact: Malware, backups, or physical access = stolen sessions
Stolen cookies can be replayed to impersonate users. No device binding or location checks.
Impact: Full account takeover from anywhere
Without HttpOnly flag, JavaScript can access cookies via document.cookie. XSS = session theft.
Impact: Single XSS exploit steals all sessions
Without SameSite protection, cookies are sent with cross-origin requests, enabling forgery attacks.
Impact: Unwanted actions performed as user
Without Secure flag, cookies are sent over HTTP in plaintext. Public WiFi = session capture.
Impact: Man-in-the-middle interception
