# UXLINK Auth

This section provides references for second sets of UXLINK's APIs:

* [UXLINK OAuth 2.0](/layer/api-and-sdk/uxlink-auth/uxlink-oauth-2.0.md): By integrating UXLINK OAuth 2.0, users can securely and conveniently log in to third-party dapps using their UXLINK-connected social accounts or popular digital wallets.
* [Ingestion API.](/layer/api-and-sdk/uxlink-auth/explorer-api.md)

### Authentication methods

{% hint style="info" %}
[Basic authentication](/layer/api-and-sdk/uxlink-auth/basic-authentication.md)

Many of X’s enterprise APIs require the use of HTTP Basic Authentication.

[OAuth 2.0 Authorization Code Flow](/layer/api-and-sdk/uxlink-auth/uxlink-oauth-2.0.md)

OAuth 2.0 User Context allows you to authenticate on behalf of another account with greater control over an application’s scope, and authorization flows across multiple devices.
