viton13.com needed one account for everything a customer does on the site: sign in, follow orders, discuss a service with the studio and keep bonuses. The studio needed one place to answer those conversations, manage members and send consent-based email.

This is VITON13’s own product: I designed and built VITON ID for our own site, and no client commissioned it. The messages on this portfolio run on the same accounts.

I defined the VITON ID number itself: 13 digits for the account type, the registration year, day and month, a five-digit sequence and a Luhn check digit. Members sign in with an email address or that number plus a password (Firebase Identity Toolkit). A new account is confirmed with a code sent by email, disposable and undeliverable email domains are refused, and in any 15 minutes one IP address gets 5 failed sign-ins per identifier and 30 attempts in total.

Around the account I built the cabinet: ten views — Overview, Requests, Messages, the VIT LIVE assistant, Saved, Bag, Orders, Health, Profile and Settings — and an eleventh, the Console, that only admins see and that loads only when opened. There admins read traffic from first-party counters, grant or deduct bonuses with a written reason, suspend or restore members and send consent-based email in batches of 50, each with a signed one-click unsubscribe.

Ordering a service opens a conversation with the studio inside the cabinet; when the studio replies, the customer gets an email, at most once per conversation every 10 minutes. Files attached to a studio order — up to three, 1.5 MB each and 3 MB in total — and the brief are encrypted in the browser with AES-GCM-256 through Web Crypto. Only ciphertext is uploaded; the key travels in the link’s #fragment, which browsers do not send to the server.

The sign-in page is live at viton13.com/viton-id and answers with noindex, nofollow, so it stays out of search results. The cabinet’s copy exists in five languages.

On 19 September 2026 the automated tests for the ID format (11 of 11), the emailed codes (3 of 3), phone linking (5 of 5), the service order flow (10 of 10), VITO bonuses (7 of 7) and the encryption (4 of 4) passed.
