<h4>Authelia (SSO) is now installed on $DOMAIN, Your Federated Computer Single Sign On</h4>
<p>
Dear Customer,<br>
We’re excited to introduce your new Single Sign-On (SSO) for Federated Core.
<br>
<br>
Your Single Sign On is called Authelia. With Authelia, a single login grants you seamless access to multiple Federated applications.<br>
Authelia provides single sign-on (SSO) access to the following Federated applications:<br>
Nextcloud, Element/Matrix, Bookstack, Jitsi, Gitea, RoundCube (Web Mail), EspoCRM, PowerDNS, and WordPress<br>
<br>
How to use Authelia<br>
• Click on any application in your Federated Dashboard and login by clicking, “Login with Authelia”<br>
• Look for a pop up that will be labeled “https://authelia.YOUR.DOMAIN”<br>
• Enter your panel user@domain.com and password, then click, “Sign In”<br>
• That’s It! You can now access all of the Applications listed above.<br>
<br>
IMPORTANT: When logging into Nextcloud through traditional login (Not Authelia) use only your 'user' and not 'user@domain.com'.<br>
<br>
Using EspoCRM or Gitea?<br>
These applications need extra configuration to work with SSO.<br>
Reply to support@federated.computer, and we’ll send you step-by-step instructions to set up SSO for them.<br>
<br>
As always, We are here to make the process simple and straightforward. Reply now if you have any questions about Authelia and we will respond promptly.
<br>
Thank you for choosing Federated Computer. We’re committed to improving your experience every step of the way.
<br>
<br>
Best regards,<br>
Federated Computer Support Team
