Flex Legacy SSO End-of-Life (EOL) Date Extended

We’ve extended the end-of-life (EOL) date for the legacy version of Flex Single Sign-On (SSO) from June 2025 to January 15, 2026. This extension comes directly in response to customer feedback and the momentum we’re seeing with migrations. Our goal is to give every team the time they need for a smooth, stress-free transition.

Here’s what customers need to do next: 

• Customers using legacy Flex SSO now have until January 15, 2026, to complete migration to the enhanced SSO.

• After this date, logins via the legacy flow will no longer be supported
