What kind of Authentication is supported by HTTP Headers?

HTTP headers support various types of authentication methods, which are used to secure access to web resources and APIs. Here are the most common types:

Basic Authentication: The client sends credentials (username and password) encoded in Base64 in the "Authorization" header, formatted as Authorization: Basic .Bearer Token Authentication: Typically used with OAuth 2.0, the client includes an access token in the "Authorization" header as Authorization: Bearer . This token verifies the user's identity and permissions.API Key Authentication: The client includes an API key in either the "Authorization" header (Authorization: ApiKey ) or as a query parameter, depending on the API.

Digest Authentication: This is a more secure form of authentication in which the credentials are hashed before being sent, and the hash is included in the "Authorization" header.

Each method offers varying levels of security based on the context and implementation.
