Resolving Two-Factor Authentication Issues in Magento 2.4+
When attempting to obtain an admin token via Magento's REST API in versions 2.4 and above, you might encounter the following error:
{
"message": "Please use the 2fa provider-specific endpoints to obtain a token.",
"parameters": {
"active_providers": [
"google"
]

Steps to Resolve:

- Ensure 2FA is set up for your admin user.
- Log in to the Magento Admin Panel.
- Navigate to your account settings and configure 2FA using your preferred method, such as Google Authenticator.
Generate Admin Token via API:

- Endpoint: POST
<BASE_URL>/rest/V1/tfa/provider/google/authenticate - Payload:
- Replace your_admin_username and your_admin_password with your actual admin credentials.

six_digit_code_from_authenticator.
{
"username": "your_admin_username",
"password": "your_admin_password",
"otp": "six_digit_code_from_authenticator"
}
Use the Retrieved Token:
- Upon successful authentication, the response will include an access token.
- Include this token in the Authorization header for subsequent API requests:
- Header: Authorization: Bearer <ACCESS_TOKEN>
