Using Ubiquiti Account and Services
This article will explain why you may want to use your Ubiquiti Account to manage your controller along with the extra services this enables.
Using your Ubiquiti account to manage your UniFi Network Controller has a number of advantages. These advantages include the ability to enabled MFA (Multi Factor Authentication), using Cloud Mail for notifications and Push Alerts for Mobile. The main disadvantage is the Ubiquiti Cloud SSO API needs to be operational for you to login to your controller.
You can enable or diable Remote Access to your controller from the UniFi Network Portal by going to Settings/System/Administration then check to enable or uncheck to disable Remote Access.
NOTE: You will need to update your controller hostname to use the "Launch Using Hostname" option in the UniFi Network Portal (https://network.unifi.ui.com) when Remote Access is enabled. This must be done using the "Legacy" User Interface as the setting is not available in the "New" User Interface. You can find it at Settings >> Network Application then update the value of "Network Application Hostname/IP" with your hosted controller domain name (example.cloudunifi.com).
Sync Local Admin with Ubiquiti SSO
Create a Ubiquiti account at (https://account.ui.com) using the same username, email, and password that you used for the local admin account you would like to sync.
NOTE: Usernames must only contain upper and lower case letters, numbers and underscore to be valid for use with a controller login. The username chosen must also be available on https://account.ui.com
(New UI) Go to System, Administration section, then select enable for "Enable Remote Access" and "Sync Local Admin with Ubiquiti SSO". Apply the changes.
NOTE: You can enable MFA (2 Factor Authentication) on your Ubiquiti account to further secure your login.
Enable Cloud Mail Server
Cloud Mail Server allows you to send email notifications, forgot password requests and invite new users. Go to Settings/System/Other Configuration then click "Cloud" as the Mail Server.
NOTE: "Remote Access" and "Sync Local Admin with Ubiquiti SSO" must be enabled to use Cloud Mail Server
Launch Controller using hostname
If launch using hostname is not working from (https://network.unifi.ui.com), you may have the example hostname set for your controller. Change to the Legacy UI, then Go to Settings/Network Application/Network Application Settings then change the value for "Network application Hostname/IP" to your controller hostname. Click "Apply Changes".
NOTE: You may get a 404 error when using the launch option from (https://network.unifi.ui.com). Simply ignore and select an option from the left navigation menu to continue.
