User account / authentication
User account / authentication adds registration, login and a personal account to the site: users save their data, see their history and orders, and sign in conveniently and securely. Less routine — more repeat visits.
User account / authentication — overview

User account / authentication is adding a login system and a personal user section to the site. A visitor registers (by email, phone or via social networks), signs in and lands in their account: profile, order history, saved addresses, favorites, reordering. We make the login secure with modern methods: passwords are stored only in hashed (one-way encrypted) form, there is password recovery and protection against brute force, and personal data is processed under the personal data law. Honestly, though: no system is 100% secure — our job is to keep the risk of a leak to a minimum and to respond properly. A simple guide to the neighboring services: you need a login and order history for retail buyers — that is an account; you need wholesale prices and roles for business clients — that is a B2B portal (see the “B2B portal” service); you need paid closed access — that is a membership site (see the “Membership site” service). If speed and a minimal budget matter, a ready authentication service (Auth0, Firebase) or your CMS’s built-in login can be cheaper — at the start we will honestly say what is cheaper in your case; we build a custom account when you need your own logic and control over the data. If you have a simple business-card site with no personal data — an account is probably not needed. Picture this: in a store a client enters their address every time and cannot see their orders — after the account they sign in, see their history and reorder in one click. The base price starts from 40,000 ₽ for registration, login and a basic account; login via each social network, integrations and extra features increase the cost — we calculate the final price by the scope.
Problems we solve
- Clients enter their data again every time — extra steps, and some abandon the purchase halfway.
- A user cannot see their orders and history — they write to support asking “what about my order”.
- There are no one-click repeat purchases — without saved data and history it is inconvenient.
- You are afraid to build the login yourself — passwords and personal data must be protected correctly, otherwise there is a leak risk.
What's included in the User account / authentication service
- Registration and login: email, phone, optionally via social networks (Google, VK)
- A personal account: profile, order history and statuses, saved addresses
- Secure password storage (hashing) and password recovery
- Protection against password brute force and basic protection against common attacks
- Reordering and favorites (for stores)
- Email or phone confirmation (optional)
- Personal data processing under the personal data law, user consents
- Responsive — a convenient account from a phone
What you get
- Clients sign in and do not enter their data again — fewer abandoned carts
- Order history and statuses are in the account — fewer questions to support
- One-click reordering — more repeat purchases
- Personal data is protected — passwords are stored only hashed, the leak risk is kept to a minimum (no one guarantees 100%), processing under the personal data law

FAQ
How is this different from a B2B portal and membership?
A B2B portal (see the “B2B portal” service) is a complex system for wholesale clients: roles, individual prices, order approvals. A membership site (see the “Membership site” service) is paid closed access by subscription. A user account is an ordinary free section for retail buyers: login, profile, order history. You need wholesale prices and roles — a portal; a paid club — membership; just a convenient login for buyers — an account.
Can there be login via Google and VK, and is there a cheaper ready solution?
Yes, we add login via social networks (Google, VK, Yandex) — it lowers the registration barrier. And if speed and budget matter, a ready authentication service (Auth0, Firebase) or your CMS’s built-in login can be cheaper: less development, but less flexibility and often a subscription. At the start we will honestly say what is cheaper in your case; we build a custom account when you need your own logic and control over the data.
How secure is it for passwords and data?
Passwords are never stored “as is” — only in hashed form, with protection against brute force and password recovery; personal data is processed under the personal data law with consents. Honestly: no system is 100% secure — we apply modern practices, minimize the risk of a leak and build in the ability to respond quickly.
