WordPress REST API JWT Authentication Method involves the REST APIs access on validation based on the JWT (JSON Web Token), Each time a request to access the API will be made, the authentication will be done against that JWT token, and on the basis of the verification of that JWT token, the resources for that API request will be allowed to access.
Download And Installation
- Log into your WordPress instance as an admin.
- Go to the WordPress Dashboard -> Plugins and click on Add New.
- Search for a WordPress REST API Authentication plugin and click on Install Now.
- Once installed click on Activate.
Use Case: Secure/Protect or authentication of WordPress REST API Endpoints using the JWT(JSON Web Token).
- Suppose you have a mobile/web application and want to allow access to the WordPress REST API endpoints based on the user capabilities such that only users with that particular capability should perform create/update operations while users with other roles can only view that. Then in such cases, you can authenticate the REST API endpoints using the JWT(JSON Web Tokens) obtained in accordance with user credentials and this method allows you to do it very securely. So, making the REST API request with this JWT passed in the Authorization header allows access to the resource/data or provides the capability/authorization to perform WordPress operation that requires particular user capability. This method provides the encryption of the token using 2 methods- HSA or RSA and valid for a limited time. Hence security is not a concern.
- The flow for WordPress REST API authentication can be achieved using the JWT method is explained below:
1. The WordPress REST API request is made with all the required parameters to obtain the JWT token. The obtained JWT token is provided in encrypted format using the HSA or RSA algorithm hence there will be utmost security.
2. Then the actual WordPress REST API request to access the resource/data or to perform operations with the WordPress database is made with the JWT token obtained in the last step is passed in the Authorization header with the token types as Bearer and our plugin will validate that JWT token and if the validation/authentication is successful then the API requester will be provided with the resource else an error response will be returned. So our plugin will act both as the JWT token provider and the JWT token validator.

Read Use Cases for the following Rest API Authentication Methods:
WordPress REST API JWT Authentication Method:
- Select your Authentication method → JWT Authentication and click on Save Configuration.
- Here you would need to make two calls:
I : Get the JWT Token
- To get the JWT Token, you would need to make an REST API Call to Token endpoint as below:
Request: POST https://<domain-name>/wp-json/api/v1/token
username = <wordpress username>
password = <wordpress password>
II : Send API Request
- Once you get the JWT token, you can use it to request access to the WordPress REST APIs as shown below:
NOTE: Above token is valid for 1 hour by default. Users have to create a token each time they want to request the API access
Check out the developer documentation for more details.
Request: GET https://<domain-name>/wp-json/wp/v2/posts
Header: Authorization : Bearer <JWT token>
