Security tokens enhance the authentication process by providing an additional layer of security and convenience. Unlike traditional passwords, which can be vulnerable to various attacks, security tokens generate a unique code or key that changes periodically, making it more difficult for unauthorized users to gain access.
For example, a security token might be a physical device, such as a USB key, or a software-based token that runs on a user's smartphone or computer. When a user attempts to log in to a secure system, the token generates a one-time password (OTP) or a digital signature that must be entered along with their regular credentials.
This multi-factor authentication (MFA) approach significantly improves security because an attacker would need to obtain both the user's credentials and their physical token or access to their smartphone app to successfully authenticate.
In the context of cloud services, security tokens can be integrated with various platforms to ensure secure access to resources. For instance, cloud providers might offer services that support OAuth or OpenID Connect protocols, which utilize security tokens to authenticate users across different applications and services.
