Obtaining a User Token Through Password and Virtual MFA Authentication

Function

This API is provided for IAM users to obtain a token through username/password and virtual MFA authentication. To use this API, ensure that virtual MFA-based login protection has been enabled for the IAM user. A token is an access credential issued to a user to bear its identity and permissions. When calling the APIs of IAM or other cloud services, you can use this API to obtain a token for authentication.

The API can be called using both the global endpoint and region-specific endpoints.

  • Obtaining a token as an IAM user

    See Request Parameters.

  • Obtaining a token using an account

    If HUAWEI ID Information is displayed on the Basic Information page of My Account, you are logged in with a HUAWEI ID. Otherwise, you are logged in with a Huawei Cloud account.

  • Obtaining a token using a HUAWEI ID

    You cannot directly use a HUAWEI ID to obtain a token. You need to create an IAM user, assign permissions to the user, and use the user to obtain a token.

  • Obtaining a token using a Huawei Cloud account

    See Request Parameters.

  • Obtaining a token as a third-party system user

    If you are a user of a third-party system, you cannot obtain a token by using the username and password that you use for federated identity authentication. Instead, you should go to the Huawei Cloud login page, click Forgot password, click Reset Huawei Cloud account password, and set a password.

  • Validity period of a token
    • The validity period of a token is 24 hours. Cache the token to prevent frequent API calling. Ensure that the token is valid while you use it. Using a token that will soon expire may cause API calling failures. Obtaining a new token does not affect the validity of the existing token.
    • The token will become invalid within 30 minutes if any of the following occurs:
      • The IAM user is deleted or disabled.
      • The IAM user's password or access key is changed.
      • The IAM user's permissions are changed (due to outstanding payments, OBT application approval, or permission modification).
    • If The token must be updated is returned when a token is used to call a cloud service API, the token has expired. You need to obtain a new token.
  • FAQs about obtaining a token

    Incorrect user name or password: Check whether the entered user name and password are correct. If the username and password are correct but the error persists, check whether you have used a HUAWEI ID to obtain a token. A HUAWEI ID cannot be directly used to obtain a token. You need to create an IAM user, grant permissions to the user, and use the user to obtain a token.

    No API access permissions: Before calling an API, ensure that you have enabled programmatic access.

Authentication failed.

  • If you are a user of a third-party system, you cannot obtain a token by using the username and password that you use for federated identity authentication. Go to the Huawei Cloud login page, click Forgot password, click Reset Huawei Cloud account password, and set a new password.
  • If your Huawei Cloud account has been upgraded to a HUAWEI ID, you cannot obtain a token using the HUAWEI ID. Instead, you can create an IAM user, grant the user required permissions, and obtain a token as the user.
