Why JWT Storage Matters

Improper JWT storage can lead to token theft and XSS attacks.


Where NOT to Store JWT

  • localStorage (vulnerable to XSS)
  • sessionStorage

Recommended Approach

Use:

  • HTTP-only secure cookies
  • Short token expiry
  • Refresh tokens

Debug JWT Easily

You can inspect token payload using our JWT Decoder tool.


Security Best Practices

  • Always use HTTPS
  • Rotate secret keys
  • Validate signature on backend

Security should never be ignored in production apps.
