OpenTech Alliance: Login Security for the DNN Customer Portal
Project overview: login security on the customer portal
OpenTech Alliance builds self-storage technology, including the INSOMNIAC customer portal. We rebuilt login security on that DNN portal, with Microsoft single sign-on for internal users and multi-factor authentication for customers.
About OpenTech Alliance
OpenTech Alliance is a self-storage technology company in Phoenix, Arizona. Its products include self-service rental kiosks, call center services, gate access control (INSOMNIAC), and operations software for self-storage operators.
The portal, in three stretches of work
The customer portal is OpenPortal, also called INSOMNIAC Online. It runs on DNN, the .NET content platform formerly called DotNetNuke.
In 2017 and 2018 we built a Bootstrap-based DNN skin for INSOMNIAC Online. That delivery included HTML templates for OpenTech's developers and a reusable CSS template per storage facility. OpenTech incorporated the skin into their solution with automated installs.
In 2019 we helped plan and test their upgrade from DNN 7 to DNN 9.
In 2025 and 2026 OpenTech brought Maxiom back for DotNetNuke expertise on the same portal. The work was DNN upgrade work and a rebuild of login security. This sets them up for the next step, DNN 10.
What we designed and built
Internal staff sign in with Microsoft single sign-on: Azure Entra ID over SAML. External customers use a custom DNN login with multi-factor authentication. At first login a customer chooses an authenticator app (TOTP), email, or SMS.
- MFA setup. A module where customers enroll the factor they chose.
- User management and phone management. Modules for the customer accounts and the phone numbers those accounts use.
- Password hashing. A move to salted password hashing, kept in sync with OpenTech's Microsoft Dynamics CRM database.
- Password migration. A tool with verify and dry-run modes.
- Account cleanup. Every user ends up with a unique email.
- Build path. A repo refactor, an automated build, and a deployment guide.
The stack is DNN on .NET Framework 4.8, C#, SQL Server, Microsoft Dynamics CRM, Azure Entra ID, SAML, TOTP multi-factor authentication, GitHub, and Azure DevOps.
We delivered the work as pull requests to OpenTech's repositories and handed it to their QA.
