Winserv WiFi corporate sign-in for UniFi (Ubiquiti) Wi-Fi
Identity governance for corporate Wi-Fi
When someone leaves, their access leaves too.
Corporate Wi-Fi sign-in through Microsoft Entra ID, formerly Azure AD (OIDC + MFA) — no on-prem Active Directory, no RADIUS, no NPS, no PKI. Employees sign in once and stay connected for 30 days; when they leave the group or the company, their network access is cut within minutes.
UniFi only. It works on top of a UniFi Controller (Ubiquiti) — that is where the portal authorizes devices. It does not work with other vendors' access points: if your Wi-Fi is not UniFi, this product is not for you.
To set it up yourself you need to be a Microsoft Entra ID administrator in your company, and your UniFi Controller must be reachable from the internet. See the requirements.

The difference is not the sign-in — it is the offboarding. The 30 days are a convenience for people who are still with you, not a grace period for people who left: every few minutes the portal reconciles the authorized group in Entra ID and cuts Wi-Fi for anyone who no longer belongs to it. On top of that, group membership is checked again at every renewal, and an operator can revoke a user from the console, which disconnects all of that person's devices at once. This is corporate identity governance, not guest marketing.
Real MFA and Conditional Access
Entra ID challenges the user with the MFA and policies you already have. The portal only orchestrates the OIDC flow; device-based policies (compliant device) need the portal's app excluded, because a captive-portal browser cannot present the device.
Sign in once · 30 days
While an employee is active, the device stays authorized for 30 days with silent renewal — sign in once and forget the portal. The window follows the employment: people who leave lose access in minutes, not in 30 days.
Nothing to run
A managed service: no server, no VPN and no UDP to open. The portal talks to your controller over HTTPS, and nothing else on your network changes.

No. The 30 days are the convenience of not signing in again while the person is active. Once they are removed from the group or disabled in Entra ID, automatic reconciliation cuts their access within minutes — and an operator can revoke all of their devices at once from the console.
No. The identity is the Microsoft Entra ID you already use. No domain controller, no NPS, no RADIUS.
No. Sign-in uses Microsoft Entra ID, whose free edition comes with any Microsoft 365 or Azure subscription and includes sign-in to unlimited apps. Each person needs an account in your company's Entra ID and to be in the authorized group; no Microsoft 365 or Office license needs to be assigned to them.
No. Entra ID's security defaults are free: when they are on, everyone registers for MFA with an authenticator app (such as Microsoft Authenticator), and Microsoft prompts for it when it judges a sign-in needs it. To require MFA on every sign-in, or to set your own rules, you need Conditional Access, which requires Entra ID P1, included in Microsoft 365 Business Premium, E3 and E5. The portal applies the rules your Entra enforces at sign-in and charges nothing extra for it. The exception is device-based rules (compliant or hybrid-joined device): a captive-portal browser cannot present the device, so exclude the portal's app from those policies.
A visitor with no account in your company gets in with a voucher — no Microsoft sign-in, and not counted in your plan. A guest account (B2B, guest type) that you put in the authorized group gets in like an employee, signing in with their own company's account, and counts as a person in your plan. Microsoft bills guests by monthly active user; the first 50,000 are free.
No. Everything runs over HTTPS: the portal reaches your controller's API over HTTPS, and devices reach the portal over HTTPS. It works behind CGNAT and on satellite links.
People who are already signed in do not notice. The UniFi controller keeps devices authorized for 30 days; only new sign-ins and renewals wait until the portal is back.
No. Authentication happens at Microsoft; the portal only orchestrates the OIDC flow and receives a token. Passwords and MFA never pass through us.
UniFi Network (Ubiquiti) only, tested on UniFi Network 10.0, 10.4 and 10.6 and on UniFi OS Server, with an open SSID and the captive portal. It does not work with other vendors' controllers. Your UniFi controller stays on your side, reached over HTTPS.
Create your portal yourself in a few minutes — or, if you would rather talk first, a 20-minute call to see whether it fits your controller.
