What is a User Authentication API?
- Definition and Purpose
A User Authentication API is essentially a conduit that empowers applications to verify the identity of users.

The Core Components of a User Authentication API
User Authentication APIs are multifaceted, encompassing various elements that collectively fortify an application’s security.
User Data Storage
This involves the secure storage of user data, often within User Databases and Repositories. Airtight encryption and data security measures are paramount to prevent data breaches, such as those that could jeopardize a WhatsApp Business API.
Authentication Methods
Authentication methods range from traditional passwords to more advanced strategies like Multi-Factor Authentication (MFA), OAuth, and Social Logins. They ensure that only authorized users gain access.
Tokens and Sessions
User sessions are managed through JSON Web Tokens (JWT), offering a secure way to identify users during their interactions with the application. Session Management is a critical aspect, distinguishing between Cookie-based and Token-based Authentication, each with its unique advantages and challenges.
