token-based authentication

Token-based authentication uses digital tokens to verify user identity. After initial login, users receive a token that grants access to resources without needing to repeatedly enter credentials.

How can native applications handle user authentication and security?

Native applications can handle user authentication and security by implementing various techniques like token-based authentication, secure storage, and secure communication. Token-based authentication involves generating a unique token for each user, which is then used to authenticate subsequent requests. This token is securely stored on the device and sent with each request to verify the user’s identity. Secure storage ensures that sensitive user data, such as passwords or access tokens, is encrypted and stored in a secure manner. Secure communication involves using encryption protocols like HTTPS to protect data transmitted between the application and the server.

How do you handle user authentication and authorization in backend systems?

User authentication and authorization are crucial aspects of backend systems. Authentication verifies the identity of a user, while authorization determines what actions they are allowed to perform. In backend systems, this is typically achieved using techniques such as tokens, sessions, and role-based access control. Tokens, such as JSON Web Tokens (JWT), are commonly used to authenticate users by providing them a unique token upon successful login. Sessions can also be used, where a session is created and stored on the server after successful authentication. Role-based access control is useful for determining what specific privileges a user has based on their assigned role. By combining these techniques, backend systems can ensure secure and controlled access for users.

How do Progressive Web Apps handle user session management and timeouts?

Progressive Web Apps (PWAs) handle user session management and timeouts by utilizing service workers to manage background tasks and cache data for offline use. They can store data locally, ensuring that users remain authenticated even when offline. PWAs typically implement token-based authentication to manage user sessions and utilize JavaScript code to monitor user activity and trigger timeouts if necessary.

What are the considerations for API security in web application development?

API security is crucial in web application development to protect against unauthorized access, data breaches, and other security threats. Some considerations to ensure API security are implementing authentication and authorization mechanisms, using HTTPS/TLS encryption, validating and sanitizing input data, implementing rate limiting and throttling, and monitoring and logging API traffic. Additional security measures include implementing strong access controls, using token-based authentication, and regularly updating and patching the API’s underlying software and dependencies.
