The standard way to handle multi-service access is account federation: one identity propagated to every service. https://www.ivpn.net/blog/moddns-beta-audited-dns-filtering-granular-controls/ Wed, 18 Mar 2026 08:53:00 +0000 https://www.ivpn.net/blog/moddns-beta-audited-dns-filtering-granular-controls/ In short modDNS is now available in beta for select IVPN customers.

Releasing a blog post titled “Why you don’t need a VPN” seemed like a bold move for some who follow IVPN. https://www.ivpn.net/blog/new-open-source-ivpn-website-subscribe-without-email/ Tue, 10 Nov 2020 11:33:25 +0000 https://www.ivpn.net/blog/new-open-source-ivpn-website-subscribe-without-email/ In a nutshell Generating an account for our VPN service no longer requires an email address, and we dropped renewing subscriptions by default in favor of a pre-paid system. We have introduced a new onboarding process with QR code setup, and two-factor authentication for account IDs that act as a sole identifier. https://www.ivpn.net/blog/ivpn-linux-app-gui-available/ Tue, 13 Oct 2020 12:08:38 +0000 https://www.ivpn.net/blog/ivpn-linux-app-gui-available/ Improving the user experience for Linux customers has been a big priority for us in 2020. Earlier this year we released a fully featured CLI app. Today, following the redesigned Android and iOS/iPadOS apps, we are releasing the next iteration of our Linux app with a graphical interface. https://www.ivpn.net/blog/redesigned-ivpn-for-android/ Mon, 28 Sep 2020 13:15:00 +0000 https://www.ivpn.net/blog/redesigned-ivpn-for-android/ After kicking off the round of releases with iOS earlier this month, today we are introducing a rebuilt IVPN app for Android. The goals for this project were similar: to deliver a solution that offers better user control, a clearer overview of connection status and location, and enables a smoother setup process. https://www.ivpn.net/blog/release-revamped-ivpn-app-iphones-ipads/ Tue, 08 Sep 2020 10:59:22 +0000 https://www.ivpn.net/blog/release-revamped-ivpn-app-iphones-ipads/ Today we are releasing redesigned iOS and iPadOS apps for IVPN.
