ZERNO · LoginSign-in for your site —
Sign-in for your site —
without your own backend
Add email, Yandex, VK or Telegram sign-in in an evening. We keep passwords, sessions and recovery; you get a client_id and a redirect URI.
The first connection is made on your ZERNO project.
- Plain OIDC: works with any framework
- Sign-in methods flip with a toggle, no site release
- Site audiences are isolated: signing in on one is not signing in on another
How to connect
- 1Create a connection. Give a redirect URI like https://your-site/api/auth/callback — get a client_id and a secret.
- 2Pick sign-in methods. Email link, Yandex ID, VK ID, Telegram, passkey. Toggled in the cabinet, not in your code.
- 3Wire it into the site. From there it is an ordinary OIDC client: redirect to the form, exchange the code for a token.
Worth knowing upfront
- A tenant is a project. Different sites do not share users — that is a choice, not a gap.
- 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.
