In 2013, it was proposed to add multi-factor authentication into Spring Security. That was the year that “selfie” was added to the English dictionary and “What Does the Fox Say?” was a viral YouTube hit.

Needless to say, one of the biggest features in Spring Security 7 is a long time coming, and is our next stop along our Road to GA.

What is Multi-Factor Authentication (MFA)?

Multi-Factor Authentication is an authentication strategy by which your identity is determined on a website by more than one means of verification, or factor. Common factors fall into one of a few categories:

• Something you know; like a password or an answer to a security question
• Something you have; like an app on your cell phone
• Something you are; like a thumbprint or other biometric

Hi, Spring fans! In this installment I talk to Oracle VP and GraalVM founder Thomas Wuerthinger, recorded at Devoxx 2025!

Continuing our Road to GA series, this week we're exploring Share Groups in Apache Kafka 4.0.0 and their integration in Spring for Apache Kafka 4.0.0 - a feature that fundamentally expands how we can consume messages from Kafka topics.

When we first start working with Kafka, the mental model is straightforward: topics hold messages, consumers read them, and processing happens in order within partitions. This partition-based model has served countless applications well, providing ordered processing with strong guarantees. However, certain use cases involve creating topics with hundreds of…

It gives me great pleasure to announce that the Spring Session Hazelcast project will now be led by the Hazelcast Team.

NOTE: This announcement is in alignment with our announcement Spring Session MongoDB: Now Led by MongoDB Team.

For ten years Spring Session has provided the infrastructure for transparently replacing session stores in a vendor independent manner. With that infrastructure in place, it is just a matter of implementing SessionRepository javadoc in order to support storing session information in a new datastore.

I cannot think of a team who has more Hazelcast experience than the Hazelcast team themselves and so it gives me great pleasure to announce the Hazelcast team will be leading the next generation of Spring Session Hazelcast! To best enable this transition, the next generation of releases will be in a new GitHub repository and have new Maven coordinates. Support for existing generations of Spring Session Hazelcast will continue to be maintained by the Spring Session team as described by the Spring Support Policy…

Hi, Spring fans! In this installment we talk to Spring Security contributor and legend Josh Cummings

This is a new blog post in the Road to GA series, this time sharing more details on the new Jackson 3 support, just a few days after Jackson 3.0.0 GA release, about to be introduced in Spring Boot 4 and related Spring portfolio projects.

Jackson is by far the most used JSON library on the JVM, and the introduction of the Jackson 3 support in Spring is the opportunity for us to provide additional enhancements, as a follow-up of the popular Jackson integration improvements in Spring that I announced more than 10 years ago!

Close collaboration between Spring and Jackson teams

When the Spring team…
