How to Obtain an Admin Token via REST API in Magento 2.4+ with Two-Factor Authentication (2FA) Enabled
Magento 2.4 and later versions require two-factor authentication (2FA) for admin users to enhance security. This means that obtaining an admin token through the standard REST API endpoint (/rest/V1/integration/admin/token) is not straightforward when 2FA is enabled. Instead, you must use the provider-specific endpoints to authenticate and retrieve the token.
Understanding the Error
When attempting to generate an admin token via the standard REST API with 2FA enabled, you may encounter the following error:
{
"message": "Please use the 2fa provider-specific endpoints to obtain a token.",
"parameters": {
"active_providers": [
"google"
]
}
}
This response indicates that you need to use the specific endpoint for your 2FA provider—in this case, Google Authenticator.
Generating the Admin Token
To generate the admin token, follow these steps:
Prepare the Request:
- Method: POST
- URL:
<BASE_URL>/rest/V1/tfa/provider/google/authenticate - Headers:
- Body:
- Replace
your_admin_usernameandyour_admin_passwordwith your admin credentials. - Replace
six_digit_otp_from_google_authenticatorwith the current six-digit code from your Google Authenticator app.
Replace <BASE_URL> with your Magento store's base URL.
Content-Type: application/json
{
"username": "your_admin_username",
"password": "your_admin_password",
"otp": "six_digit_code_from_authenticator"
}
Send the Request:
- Use a tool like cURL, Postman, or any HTTP client to send the POST request.
- This token is used for subsequent API requests.

Using the Admin Token
For subsequent API requests, include the token in the Authorization header:
Authorization: Bearer <ACCESS_TOKEN>
Replace <ACCESS_TOKEN> with the token received in the previous step.
Alternative Method: Integration Tokens
If you prefer not to use 2FA for API access, you can create an integration token:
Create an Integration:
- In the Magento Admin panel, navigate to
System > Extensions > Integrations. - Click
Add New Integration. - Fill in the necessary details and set the Resource Access to All.
- Save and activate the integration.
By following these steps, you can successfully obtain and use an admin token in Magento 2.4+ with 2FA enabled.
