token-based authentication

Token-based authentication is a method used to verify a user's identity when accessing a system or service. Instead of using a username and password for every request, the user logs in once and receives a unique token, like a digital key. This token is then sent with each request, allowing the system to recognize and authorize the user without requiring their login details repeatedly. This approach enhances security, simplifies the user experience, and is commonly used in web applications and APIs, ensuring that only the right users have access to specific resources.
