RBAC (Role-Based Access Control)
Role-based access control (RBAC) governs what users can do by assigning them roles — such as admin, member, or viewer — that carry defined permissions, rather than granting rights to each person individually. It scales access management: change a role's permissions once and every user with that role updates, and onboarding becomes assigning a role, not wiring up dozens of grants.

RBAC adds a layer between users and permissions. Instead of attaching capabilities directly to each person, you define roles that bundle a set of permissions, then assign people to roles. A new engineer becomes a 'member'; a team lead becomes an 'admin.' Their concrete rights — what they can read, edit, or delete — flow from the role, so access is described in terms of what someone is, not an ad-hoc list of what they may touch.
The model's strength is manageability at scale. Auditing 'who can delete a project' means inspecting a few roles rather than every user. Adjusting policy means editing one role definition instead of hundreds of individual grants. And the principle of least privilege becomes practical: give each role only the permissions its work requires, and people inherit exactly that, no more.
RBAC is one layer of authorization, not the whole story. In multi-tenant systems it sits alongside tenant isolation — a role says what you can do, while row-level security ensures you only ever do it to your own workspace's data. The two compose: tenancy bounds which rows exist for you, RBAC bounds which actions you may take on them.

- Row-Level Security (RLS)Row-level security (RLS) is a database feature that restricts which rows a query can read or modify based on the current user or context. Instead of relying solely on application code to filter data, the database itself enforces access policies on every query — a strong defense for multi-tenant systems where one workspace's data must never leak to another.
- Multi-TenancyMulti-tenancy is an architecture where one running application and database serve many independent customers (tenants), with each tenant's data strictly isolated from the others. It lets a SaaS product share infrastructure for efficiency while guaranteeing that one workspace can never see another's data — a guarantee enforced in the data layer, not left to hope.
- SSO (Single Sign-On)Single sign-on (SSO) lets users access many applications with one set of credentials, authenticating through a central identity provider instead of a separate login per app. Sign in once and you're recognized everywhere connected. SSO improves security and user experience at once — fewer passwords to reuse or forget, and centralized control over who can access what.
- Audit TrailAn audit trail is an append-only, time-ordered record of who did what, when, and to which object across a system. Every create, edit, delete, and approval is logged immutably, so any state can be traced back to the actions that produced it. Audit trails underpin accountability, debugging, compliance, and — increasingly — oversight of what AI agents do.
