Identity is not bolted on — sessions, JWT, database, and security rules share one user context.

Identity data stays in your environment
Manage users, sessions, and linked identities, and connect accounts to your business data.
Good identity is not just another login page.
It lets your code stop guessing who sent each request.
CloudBase product design principleIdentity · Session · Authorization
From consumer sign-in to service authorization,
every layer knows the current user
WeChat identity
- Official account & Open Platform OAuth
- OpenID / UnionID link users
- Trusted WeChat context on the server
- Works with data security rules
Custom login
- Connect existing business accounts
- Map to CloudBase user identity
- Link with WeChat identity
- Reuse platform resource access
Roles & policies
- JWT groups enter authorization context
- Layer anonymous and authenticated users
- Database RLS down to each row
- OPA policies guard service entry points
Pick a sign-in entry,
use the same identity API

PostgreSQL reads the current user from JWT claims; policies define ownership and operations alongside tables.
