Why is it not recommended to store sensitive data in localStorage?

Storing sensitive data in localStorage is not recommended for several reasons:

• Lack of encryption: Data in localStorage is stored in plain text, and any script on the page can access it.
• Vulnerability to XSS attacks: If the site has vulnerabilities like Cross-Site Scripting, an attacker can execute malicious scripts and access localStorage.
• Data is accessible on the client side: Users or malicious software on their device can easily read or modify the data.
• No automatic deletion: Data in localStorage persists indefinitely until explicitly removed, increasing the risk of compromise.

For storing sensitive data, it is better to use secure HTTP-only cookies or server-side sessions.
