Application Access Token
An application access token is like a digital 'all-access pass' that proves who you are to a computer system. If a hacker steals this pass, they can walk right into your account and use your services without needing your password, which is a major security risk for things like AI chatbots or cloud storage.
An application access token is a credential, such as an OAuth bearer token or API key, that grants a client temporary authorization to interact with an API. Adversaries target these tokens to bypass standard authentication flows, allowing them to impersonate a legitimate user or service to access sensitive AI models, SaaS platforms, or cloud resources.
An application access token is a cryptographically signed or opaque string representing an authorization grant, typically issued by an identity provider (IdP) following successful authentication. In the context of AI security, these tokens facilitate delegated access to LLMs, inference APIs, and vector databases. Adversaries leverage stolen tokens to perform session hijacking, bypassing multi-factor authentication (MFA) and credential-based controls to execute unauthorized API requests and exfiltrate proprietary data or model outputs.
