UUID Use Case

UUID Account ID

Whether you call it account, organisation, or workspace, a UUID id keeps tenants isolated and their identifiers unguessable.

What Is UUID Account ID?

Every resource should be scoped to an account UUID, so a missing auth check cannot cross into another tenant.
The UUID's unguessability means a typo or bug is unlikely to hit a real other account.

How to generate

Create accounts with UUID ids.
Scope rows by account_id in every query.
Enforce at the data-access layer, not just the UI.

Use Cases

SaaS workspaces.
Agency client accounts.
Reseller sub-tenants.

Code Examples

PostgreSQL

SELECT gen_random_uuid();

Python

import uuid
id = uuid.uuid4()

Frequently Asked Questions

Account UUID vs user UUID?

Separate them — an account owns many users; conflating the two breaks multi-user tenancy.

Do I need both account and user IDs in a URL?

Usually account is implicit from auth; only include user id when addressing a member.
