- Store hashed with a use-count or expiry.
- Redeem on signup; revoke from admin.
Use Cases
- Beta access.
- Private communities.
- Referral links.
Code Examples
JavaScript
const id = crypto.randomUUID();Python
import uuid
id = uuid.uuid4()Frequently Asked Questions
Single or multi-use invite?
Single-use for tight control; multi-use (capped) for shareable beta links.
Should the code be in the URL?
Yes, as a capability link — but keep it revocable and monitor redemption.
