Access Token

Why This Matters Now: The recent data breach at a major cloud provider exposed thousands of access tokens, putting countless applications and sensitive data at risk. As of November 2023, this incident has highlighted the critical need for robust access token management and protection strategies. 🚨 Breaking: A major cloud provider's data breach exposed thousands of access tokens. Implement strong token protection measures now. 1000+Tokens Exposed 48hrsTo Respond Understanding Access Tokens Access tokens are a core component of modern authentication and authorization protocols, such as OAuth 2.0 and OpenID Connect. They are used to grant clients temporary access to protected resources without requiring the user’s credentials on every request. However, the very nature of their temporary and valuable nature makes them prime targets for attackers. ...

The Client Credentials Flow is a foundational grant type in OAuth 2.0, designed for machine-to-machine (M2M) communication scenarios where no end-user is involved. This flow lets you securely backend services, daemons, or microservices to authenticate themselves and access protected APIs without user interaction.
