API Authentication methods
Thread 🧵👇
Thread 🧵👇
Here, we'll discuss the three most commonly used API authentication techniques:
- HTTP Authentication
- API Keys (Bearer token, JSON Web Token)
- OAuth

1.1. Basic HTTP Auth
Sending login information to a server may be done using HTTP Basic authentication.
The credentials are sent in an HTTP header, making them easily interceptable.

The credentials are sent in an HTTP header, making them easily interceptable.
It lessens the security of HTTP Basic authentication in comparison to the other techniques mentioned above.
1.2 Bearer HTTP Auth
To access a resource, the user must first authenticate using a bearer authentication, which often takes the form of a card or key.
A username or other identity is often embedded within the token.
Authorization: Bearer <token>
To access a resource, the user must first authenticate using a bearer authentication, which often takes the form of a card or key.
A username or other identity is often embedded within the token.
Authorization: Bearer <token>
1.3 JWT - Json Web Token
Only application-level security is provided via the API key (described below). It provides equal access to all users.
The JWT token, on the other hand, offers user-level access.

The JWT token, on the other hand, offers user-level access.
Additional details, such as the expiration date and the user's ID, are possible.
2. API Keys
An API key is a unique string/code used to access APIs.
Usually, it is a lengthy list of letters and numbers.
Users' identities and use patterns are tracked via API keys.

3. OAuth
OAuth is an open standard for authorization that provides a way for users to grant third-party access to their web resources without sharing their passwords.
It also allows for secure access to those resources by ensuring that only authorized users can access them.
