How do I recover my username and password in REST API?

The most simple way to deal with authentication is to use HTTP basic authentication. We use a special HTTP header where we add ‘username:password’ encoded in base64. Note that even though your credentials are encoded, they are not encrypted!

What is difference between OAuth and OAuth2?

OAuth 1.0 only handled web workflows, but OAuth 2.0 considers non-web clients as well. Better separation of duties. Handling resource requests and handling user authorization can be decoupled in OAuth 2.0. Basic signature workflow.

How can I secure my API without authentication?

you should look at OAuth for the authorization , and the connection should always be HTTPS, so the packets can’t be easily sniffed. To use this without authentication is pretty insecure, as anybody could attempt to impersonate a valid client. Having the connection HTTPS would only slow down a hacker.

Which authentication is best for web API?

OAuth 2.0 is the best choice for identifying personal user accounts and granting proper permissions. In this method, the user logs into a system. That system will then request authentication, usually in the form of a token.

What is HTTP basic authentication and how it works?

HTTP basic authentication is a simple challenge and response mechanism with which a server can request authentication information (a user ID and password) from a client. The client passes the authentication information to the server in an Authorization header. The authentication information is in base-64 encoding.

Is basic authentication secure?

Basic authentication is simple and convenient, but it is not secure. It should only be used to prevent unintentional access from nonmalicious parties or used in combination with an encryption technology such as SSL.

What is OAuth authentication REST API?

OAuth is an authentication protocol that allows a user (resource owner) to grant a third-party application (consumer/client) access to their information on another site (resource).

How token based authentication works in REST API?

How token-based authentication works in Rest ApiThe client sends their credentials (username and password) to the server.The server authenticates the credentials and generates a token.The server stores the previously generated token in some storage along with the user identifier and an expiration date.The server sends the generated token to the client.More items…•

How does OAuth 2.0 authentication work?

It works by delegating user authentication to the service that hosts the user account, and authorizing third-party applications to access the user account. OAuth 2 provides authorization flows for web and desktop applications, and mobile devices.

Involves checking resources that the user is authorized to access or modify via defined roles or claims. For example, the authenticated user is authorized for read access to a database but not allowed to modify it. The same can be applied to your API.
