Enabling MFA for your account

{: #enablemfa}

As an {{site.data.keyword.Bluemix}} account owner or administrator for the billing service, you can choose to require multifactor authentication (MFA) for every user in the account or just users with IBMids who do not use single sign-on (SSO). {: shortdesc}

Before you begin

{: #considerations}

Review the following considerations before you enable IBMid MFA for your account to ensure that you know how it affects all users in your account:

  • Enabling MFA in your account affects all members of the account. This means that if users of your account are members of multiple {{site.data.keyword.cloud_notm}} accounts, they must enroll for MFA at their next login even if they don't intend to use resources in the secured account.
  • API keys for users and service IDs continue to work after MFA is enabled.
  • If you require the use of CLI or UI login into Cloud Foundry, you must use API keys or SSO after MFA is enabled for the account.
  • MFA for your account applies to a user's login, but does not apply to API calls. If a user has permission to make API calls to resources in your account, the user can do so without completing MFA. If the user belongs to other accounts, the user can make API calls to resources in your account by using an API key from an account that did not require MFA.
  • Plan a communication and support strategy for users in your account:
    • Choose a date and time that you plan to enable MFA that results in the least impact to your business.
    • Notify your account users after you enable MFA with information on how to get set up.

When the MFA setting is enabled, all IBMid users in your account are prompted for IBMid MFA authentication upon login. If you have other MFA factors set up for any IBMid users in your account, they are no longer prompted for those MFA factors. For example, if you previously enabled 2FA in the customer portal for your classic infrastructure resources, the MFA account setting overrides the 2FA option. {: tip}

You can also enable and disable MFA in your account on the Verification methods and authentication factors{: external} page by clicking Show accounts > Manage your own account. {: note}

Enabling MFA

{: #enabling} {: help} {: support}

To enable MFA, you must be the account owner or an administrator for the billing account management service. Enabling MFA does not affect users that are already logged in, as the enforcement of MFA on the account takes effect only at new logins. Make sure that you notify your account users that MFA is enabled, and describe the impact to users at their next login.

  1. In the {{site.data.keyword.cloud_notm}} console, go to Manage > Access (IAM) > Settings.
  2. Click Edit in the Authentication section.
  3. Select the type of MFA to enable in your account.
    • MFA for users with an IBMid: Require users to authenticate by using an IBMid, password, and time-based one-time passcode (TOTP). You can enable this option for all users or non-federated users.
    • MFA for all users (IBMid & supported IdPs): Require users to authenticate by using one of the following MFA factors. This option applies to users who are using either an IBMid or an external identity provider (IdP).
      • Email-based MFA: Users authenticate by using a security passcode that's sent in an email.
      • TOTP MFA: Users authenticate by using a TOTP.
      • U2F MFA: Users authenticate by using a physical hardware-based security key that generates a six-digit numerical code. Based on the FIDO U2F standard, this factor offers the highest level of security.
  4. Click Update.

The first time that you log in to your account after MFA settings are updated, you need to verify your identity by using two different verification methods. Methods for verification include email, text, or phone call, and you can use any combination of those options to verify your identity. After you verify your identity, you set up your authentication factors. If you need to update your verificaiton methods or authentication factors later, see Managing verification methods and MFA factors. {: note}

Disabling MFA

{: #disablemfa}

To disable MFA, you must be the account owner or an administrator for the account management billing service. Disabling MFA does not affect users that are already logged in. The action takes effect at all new logins.

  1. Go to Manage > Access (IAM) > Settings in the {{site.data.keyword.cloud_notm}} console.
  2. Click Edit in the Authentication section.
  3. Select None.
  4. Click Update.
