Introducing MFA for IBM Cloud Users with Federated ID
By: Ben Lopez, Martin Smolny, and Michelle Kaufman
Multifactor authentication for IBM Cloud users
We are excited to deliver a highly requested feature to our IBM Cloud account owners that supports multifactor authentication (MFA) for federated IDs. A user with a federated ID can log in by using their corporate or enterprise single sign-on (SSO) ID. The enhanced MFA functionality now allows account owners or users with the administrator role on the billing account management service to enable MFA for all users in the account, whether they have a federated or non-federated ID.
For those unfamiliar with MFA, it is also known as two-factor authentication. It adds an extra layer of security to the login process by requiring a user to provide a time-based, one-time passcode (TOTP) that is set up using an authenticator app in addition to their standard ID and password. To put it simply, MFA support strengthens security by preventing unauthorized account access and protecting your data.
What you need to know about enabling MFA
While this is exciting news, there are a few things all account owners and billing service administrators should know prior to enabling MFA for their users for the first time:
- When MFA is enabled, users need an authenticator app. We will walk users through how to get the authenticator app on a smartphone device via our UI when they log in.
- Any user without an authenticator app won’t be able to log in because after MFA is turned on, every user is required to provide their passcode the next time they log in.
- If you require MFA for your account and you have users in your account that do not have an IBMid, you must enable one of the other MFA options for that user from their User details page in the IBM Cloud console. For more information, see Types of MFA.
- If you are using CLI, you must use API keys or SSO after MFA is enabled for the account.
Before you turn on MFA, we recommend alerting all IBM Cloud users of the upcoming change and providing instructions for configuring the authenticator smartphone app. These two practices will help prepare your users for the change and prevent any login delays when you enable MFA.
