Description: A user token is a data fragment that represents a user’s identity in a computer system. This token can contain information such as the username, the user’s unique identifier, and other relevant attributes that allow for authentication and authorization within an application or service. Tokens are fundamental in identity and access management, as they enable systems to verify a user’s identity without the need to store passwords directly. Additionally, tokens can be temporary or permanent, and their use has become essential in the context of multifactor authentication, where an extra layer of security is required. The implementation of user tokens helps prevent unauthorized access and protects sensitive information, ensuring that only authenticated users can access specific resources. Today, tokens are used in various applications, from web services to mobile applications, facilitating a more secure and efficient user experience.
