Sign-in for your site that keeps
user data inside Russia
Plain OIDC — works with any framework. Your users' accounts are stored in Russia, as 152-FZ requires. Email, Yandex ID or VK ID sign-in takes an evening, no backend of your own.
The first connection is made on your ZERNO project.
- We keep passwords, sessions and recovery; you get a client_id and a redirect URI
- Sign-in methods flip with a toggle, no site release
- Site audiences are isolated: signing in on one is not signing in on another

Why this holds up
Data stays in RussiaServers and backups sit in the JSC Datacenter facility in Khimki, Moscow Region. Not a Russian company — a Russian facility.
We run on it ourselvesDrops, audit, models, social and the agency all sign people in through it. If it goes down, we go down with you.
One account for everythingThe same account opens every ZERNO service and the shared rouble balance. That is the ONE in the name.
How to connect
- 1Create a connectionGive a redirect URI like https://your-site/api/auth/callback — get a client_id and a secret.
- 2Pick sign-in methodsEmail link, Yandex ID, VK ID, passkey. Toggled in the cabinet, not in your code.
- 3Wire it into the siteFrom there it is an ordinary OIDC client: redirect to the form, exchange the code for a token.
Beyond the sign-in itself
Sign-in sits at the single point every one of your users passes through — and sees what the site itself never does.
Events land in your databaseNew person, sign-in, verified email, merged accounts — we call you, signed, with five retries over a day. No polling our API.
You see who came back and who vanishedWho signed in this week, how many are new, what share ever returned, who has been asleep for a month. No analyst required.
You see who would be locked outThe cabinet says upfront who has neither a verified email nor a passkey: turn that method off and those people lose access.
It is plain OIDC — this is the whole integration
No SDK of ours: any library that speaks OpenID Connect works with us out of the box.

Going over does not switch sign-in offIf you pass the plan's actives, sign-in keeps working — we write to you and move you up from the next month. Cutting off your users' login is not how we remind you to pay.
Security is not sold separatelyEverything sign-in can do to protect an account — second factor, secret rotation, audience isolation — works on every plan, the free one included. We sell scale and paperwork, not the right to protect your users.
One balance for every serviceThe sign-in subscription is charged to the same rouble balance as drops, social and models. Top up by Russian card, SBP or an invoice with closing documents.
Worth knowing upfront
- Each site keeps its own user base: signing in on one is not signing in on another.
- The user profile belongs to your site. We own the sign-in, not your customers' account pages.
- Secrets rotate without reinstalling; the old one stops working immediately.
