Google Cloud Will Require MFA by the End of Next Year
Google Cloud plans to establish mandatory multi-factor authentication by the end of 2025. This month (November 2024), Google Cloud will begin encouraging the 30 percent of users who have not yet adopted MFA to do so. In early 2025, Google Cloud will start 'requiring MFA for all new and existing Google Cloud users who sign in with a password.' By the end of 2025, Google Cloud expects to 'extend the MFA requirement to all users who federate authentication into Google Cloud.' They will offer flexible options for MFA adoption.
Editor's Note
This is a welcome move by Google, and to be frank, mandatory MFA should be considered as table stakes for any cloud service provider.

The time for passwords as the single method of authentication has come to an end. Kudos to Google and other tech companies for 'forcing' transition to multi-factor authentication. This will make credential harvesting much more difficult for the adversary. Well done in setting an end date.

Google has been a leader in promoting strong authentication (at least two kinds of evidence, at least one of which is resistant to replay). Its solutions have offered users options that minimize any inconvenience. For example, passkeys are both more secure and more convenient than passwords. In part to avoid alienating users and customers, Google has offered, not mandated, strong authentication. It is now clear that in most applications, clearly so in infrastructure applications, relying on fraudulently reusable passwords is reckless. While the end date that they have set, end 2025, seems inconsistent with the urgency of the situation, it is probably proportionate to the size of the effort. Let us hope for early progress.

I may sound like a broken record, but MFA needs to be ubiquitous. Google is taking a three-phase approach, with notification and reminders, and you don't have to wait to implement MFA. Given the publicity, assume attackers will work to take advantage of remaining password-only accounts. Google will integrate with existing MFA in your IDP or you can use their MFA, meaning there is no reason to not succeed here.
