What are some secure authentication methods for Express applications?
There are several secure authentication methods for Express, including JWT (JSON Web Tokens), OAuth, and session-based authentication.
Can you explain how JWT works in Express?
Sure! JWT allows you to securely transmit information between parties as a JSON object. It is compact, URL-safe, and can be verified and trusted because it is digitally signed.
What are the advantages of using OAuth?
OAuth allows users to grant third-party applications access to their information without sharing their passwords, enhancing security.
Are there any libraries you recommend for implementing these methods?
Yes, for JWT, you can use 'jsonwebtoken'. For OAuth, 'passport' is a popular choice that integrates well with Express.
