Three different authentication methods exist to access the Twitter enterprise APIs. Each of these methods is described below.
HTTP Basic Authentication
OAuth 1.0a (user context)
OAuth 2.0 Bearer Token (application-only)
HTTP Basic Authentication
How it works
Most of Twitter’s Enterprise APIs require HTTP Basic Authentication. This consists of a valid email address and password combination passed as an authorization header for each API request.
Username and password.This username and password combination is the same login credentials (email address and password) used to log in to the enterprise console.
OAuth 1.0a (sometimes also referred to as “user context authentication”) allows you to make API requests on behalf of a Twitter user. This authentication method allows you to send your developer App’s Consumer Keys (API Key and Secret), alongside a set of user access Tokens (Access Token and Secret), as part of the authorization header in the API request.
While the Consumer Keys give the API context about the developer App that is sending a request, the Access Tokens provide context about the Twitter user on behalf of whom the App is sending the request.
All write actions and all reading of protected data using the Twitter API require OAuth 1.0a, and the Access Tokens must belong to the owning user. For example, in the case of posting a Tweet, the Access Tokens must belong to the user on behalf of whom you are posting the Tweet. Similarly, if you are accessing private engagement metrics with the Engagement API, the Access Tokens must belong to the user who owns the Tweet(s) and related protected data.
If the user behind a request is yourself (in other words, the Twitter account that owns the developer App) the required Access Tokens can be generated directly from within the developer portal (under the “Keys and tokens” tab for your developer App).
For all other Twitter accounts, users must first authorize your developer App for access. A user can grant your developer App access by undergoing the 3-legged OAuth flow, which in turn allows you to obtain the user’s Access Tokens. You can then use these Access Tokens to authenticate your request and make a request on behalf of the user.
Information on how to obtain a user’s Access Tokens is included in the articleOAuth 1.0a: how to obtain a user’s access tokens.
Information on how to authorize a request using OAuth 1.0a can be found in our documentation.
Prerequisite
An approved Twitter developer account (if you don’t have one, you can apply for access).
These can be generated in your developer portal, under the “Keys and tokens” tab for your developer App.
2. User Access Tokens (Access Token and Secret).
If you are making a request on behalf of your own account, these can be generated in your developer portal, under the “Keys and tokens” tab for your developer App.
If you are making a request on behalf of another user, you can obtain these Access Tokens via the 3-legged OAuth flow. You can read more about how to do this below: OAuth 1.0a: how to obtain a user's access tokens.
OAuth 2.0 Bearer Token (application-only)
How it works
OAuth 2.0 Bearer Token allows you to make API requests on behalf of your Twitter developer App. This authentication method is also sometimes referred to as “application-only authentication” because the credentials you send as part of the request give the API context about your developer App. Compared to OAuth 1.0a user context authentication, OAuth 2.0 Bearer Token does not involve any Twitter user(s). This authentication is typically used for read-only access to publicly available information (for example, accessing public Tweets).
Prerequisite
Approved Twitter developer account (if you don’t have one, you can apply for access).
Consumer Keys (API Key and Secret) or a Bearer Token.These can be generated in your developer portal, under the “Keys and tokens” tab for your developer App.

There are several authentication types. For user identity, users are typically identified with a user ID; authentication occurs when the user provides credentials, such as a password, that match their user ID. The practice of requiring a user ID and password is known as single-factor authentication (SFA).
There's a wide variety of authentication methods available, ranging from a simple single password to complex multi-factor authentication, including passwords, one-time codes and biometrics.
Passwords are the most common methods of authentication. Passwords can be in the form of a string of letters, numbers, or special characters. To protect yourself you need to create strong passwords that include a combination of all possible options.
Authentication is verifying the true identity of a user or entity, while authorization determines what a user can access and ensures that a user or entity receives the right access or permissions in a system. Authentication is a prerequisite to authorization.
External hardware keys, like Yubikeys, are among the strongest authentication factors available. Also called FIDO keys, they generate a cryptographically secure MFA authentication code at the push of a button.
