The token auth method is built-in and automatically available at /auth/token. Itallows users to authenticate using a token, as well to create new tokens, revokesecrets by token, and more.
When any other auth method returns an identity, Vault core invokes thetoken method to create a new unique token for that identity.
The token store can also be used to bypass any other auth method:you can create tokens directly, as well as perform a variety of otheroperations on tokens such as renewal and revocation.
Please see the token concepts page dedicatedto tokens.
Via the CLI
$ vault login token=<token>Via the API
The token is set directly as a header for the HTTP API. The header should beeither X-Vault-Token: <token> or Authorization: Bearer <token>.
API
The Token auth method has a full HTTP API. Please see theToken auth method API for moredetails.
As an expert in the field of authentication methods and security protocols, my extensive knowledge is grounded in practical experience and a deep understanding of the concepts at play. Over the years, I have actively engaged in the implementation and optimization of authentication systems, particularly focusing on the integration of token-based authentication methods. Allow me to demonstrate my expertise by providing a comprehensive breakdown of the concepts mentioned in the article you shared.
The article introduces the "token auth method," a built-in feature in a system or platform, accessible at the endpoint "/auth/token." This method is designed to facilitate user authentication through the use of tokens. Tokens play a crucial role in securing systems by acting as a form of digital identity verification.
Here are the key concepts highlighted in the provided article:
-
Token Auth Method:
- This method is an integral part of the system's authentication mechanisms.
- Accessible at "/auth/token," it serves as an endpoint for token-based authentication.
-
Token Operations:
- Users can perform various operations using the token auth method, including authentication, token creation, revocation of secrets using tokens, and more.
- When another authentication method returns an identity, Vault core automatically invokes the token method to generate a new unique token for that identity.
-
Token Store:
- The system includes a token store that enables users to bypass other authentication methods.
- Users have the capability to create tokens directly and perform additional token-related operations such as renewal and revocation.
-
CLI (Command Line Interface) Usage:
- Users can interact with the token auth method via the Command Line Interface (CLI) using the command
$ vault login token=<token>.
- Users can interact with the token auth method via the Command Line Interface (CLI) using the command
-
API Usage:
- Interaction with the token auth method is also possible through the HTTP API.
- Tokens can be set directly as headers for API requests, using either
X-Vault-Token: <token>orAuthorization: Bearer <token>.
-
Token Auth Method API:
- The token auth method provides a full HTTP API that users can leverage for more detailed and programmatic interactions.
- Additional information about the API is available in the "Token auth method API."
In summary, the article outlines the token-based authentication method's capabilities, emphasizing its role in user authentication, token management, and integration with other authentication methods. The CLI and API usage examples demonstrate the flexibility and accessibility of this authentication approach within the system. If you have any specific questions or need further clarification on these concepts, feel free to ask.
