Access to OBFSN is one subscription per account. It is not tied to a particular phone or computer: you get a personal link and import it into an app on each of your devices. Everything is managed at app.obfsn.com, which also opens as a Mini App inside the @obfsnbot bot. It is the same place with the same data; only the way in differs.
The link looks like https://subscription.obfsn.com/c/<token> and replaces manual setup. It already holds all our servers and both protocols, VLESS Reality and Hysteria2. The app fetches the list through that link and refreshes it by itself: when we add or change a server, you have nothing to reconfigure.
The link is personal and it opens your access. Do not publish it or forward it to anyone.
The link has a device counter. You can see what is connected on the My devices page, and unlink whatever you no longer need there, an old phone or a computer you have stopped using. A device counts as active if it has been in touch in the last 24 hours; inactive ones drop off the list on their own over time.
The trial is 7 days, issued once, from a button in the bot or in your account. After that, access is extended on the payment page: SBP through YooKassa, Telegram Stars or your internal balance. A promo code adds subscription days.
Days can also come for free: for inviting friends, for tasks and XP, and as a bonus for subscribing to the @obfsn channel.
You can share the subscription with the people close to you in the VPN sharing section. Their access runs as long as the payer's subscription does: when it ends, so does theirs.
Installing an app and importing the link are covered in the setup guides. There are guides for iOS, Android, Windows, macOS, Android TV, Apple TV and the browser extension.
