Upgrading From MultiSSOv1 to MultiSSOv2
We love the extra features and functionalities that plugins provide, but we occasionally have to phase out support for some of them. This helps make sure we can bring you new and even more useful options.
Beginning with the Now Platform Rome release in September 2021, we no longer deploy or activate the Multiple Provider Single Sign-On v1 feature (MulitSSOv1). They will remain active in your instance, including when you upgrade to a new release family.
Beginning with the Now Platform Tokyo release planned for September 2022, we will end support for the MultiSSOv1feature. While they will remain active in your instance, including when you upgrade to a new release family, the SSO functionality will not be supported by the MultiSSOv1 version. To use SSO functionality you have to upgrade to the MultiSSOv2 version and if you continue to use MultiSSOv1 logins may break.
MultiSSOv2 version comes with a lot of enhancements like HTTP POST Support, IDP initiated Single Logout (SLO) support, Encrypted Assertion support, and Seamless Upgrades along with a host of other improvements.
