Give userscross-platform digital identity
UserMatrix (UM) is a user identity infrastructure incubated by the Yunjii team. From an OAuth login tool to a federated identity platform powering 1700+ apps.
Ourstory
The Yunjii product matrix started in early 2026, launching 17+ apps including Yunjii Tong, Yunjii Media, Yunjii Studio, and Yunjii AI. Each app needs login, permissions, and user management.
Initially each app wrote its own login code, and problems emerged: users logged in via WeChat on Yunjii Tong had to log in again on Yunjii Studio; the same user had different identities across apps, data couldn't flow; permission management was siloed, B-end consoles were reinvented repeatedly.
UM was born from this pain — transforming user identity from an "app accessory" to a "user's digital asset". One UMID runs through all apps, cross-platform accounts auto-merge, user data belongs to the user.
Now UM is open to the public, letting more teams enjoy this infrastructure. From open-source SDK to SaaS subscription, from SaaS to private license, there's a plan for you.
