This extension equips Flarum with Single Sign On (shortly SSO). Basically, this extension will act as a bridge between Flarum and your SSO/Auth system. The extension is useful if you run Flarum on a subdomain but you want to use the login mechanism of your main website.
If you have an OpenID Connect provider/auth system you can use my OpenID Connect Client Extension, that requires zero coding from your side. You only have to configure it and you’re ready to go!
Workflow based on this post.
The user wants to login to your Auth system. Once his login attempt is successful, a POST request is sent to Flarum API from one of the extension plugins to retrieve the user access token (verifying his credentials). He will be created in the Flarum database (through an API request) if he isn’t signed up on Flarum.
Then, the access token is saved in a cookie to be used when the user visits Flarum (this cookie keeps the login active).
This section covers the difference between plugins and addons.
This is the standard Flarum extension, installable on Flarum following the Installation instructions. This is required since it activates the user when he is added to the database, manage his logout, changes the Login and Signup links destination, …
A plugin is a library/package that you install on your Auth system to communicate with Flarum. This allows you to login, signup, update or logout the user (these are only examples, there may be other features along these ones). Some plugins are already developed for you and needs only to add the proper settings, like the WordPress plugin.
Examples of plugins are the PHP and WordPress ones. You can find them in the “Plugins” section in the left sidebar.
Addons are additional features that can be added to the plugin(s). The installation method changes with the plugin you are using. For example, with the PHP plugin you have to add an addon calling an object method, while on WordPress you need to install it through the plugins screen.
Examples of addons are the Groups and the JWT ones.
Install by executing the command below and activate the extension in Flarum Administration area.
composer require maicol07/flarum-ext-sso
You’ll also need a plugin to get it work with your auth system. You can choose one from the “Plugins” section in the left sidebar.
PHP versions will be supported until its EOL.
If Flarum core changes PHP version before the official EOL, I’ll update too the version accordingly to what they have chosen.
Upgrade by executing the command below, like with every other extension.
composer update maicol07/flarum-ext-sso
Here is the explanation of all the extension settings:
Signup URL: URL where the user will be redirected when the Signup button is clicked
Login URL: URL where the user will be redirected when the Login button is clicked
Logout URL: URL where the user will be redirected when the Logout button is clicked
Manage account URL (available in 1.8+): URL where the user will be redirected whenthe Manage Account button is clicked. This button shows up in the user settings only if this setting has a valid URL.
Open account management in a new tab (available in 1.8+): Open the link of the Manage Account button in a new tab
Remove login button: Removes the login button from Flarum frontend
Remove signup button: Removes the signup button from Flarum frontend
Cookies name prefix: Prefix of the token cookie. Set by default to “flarum”
Provider mode: Enable this option to use the provider mode (SSO between Flarum instances).
Allows other Flarum instances to login an user of this Flarum instance.
This will disable the standard SSO feature with other websites.
Default values for WordPress are:
redirect_to=forumpart is important as it will redirect your users back to the forum)
issclaim of your JWT. This is the domain that issues the JWT. Typically, this corresponds with the root domain.
This addon requires the
lcobucci/jwt:>=4.1 package added (and installed) to Flarum
composer.json to work.

You can enable provider mode to register Flarum instances as clients and login users with your provider Flarum account.
To do so, you must obtain an API key and a password token for each Flarum client you want to add (check in the PHP plugin options how to obtain them).
Then you have to enable the “Provider mode” in the main flarum instance you want to be the provider and register clients with their parameters:
In the client Flarum you have to set it up normally, but you have to set the Cookie prefix setting this way: if the client name is filled in provider, then the cookie prefix is the client name, otherwise it will be equal to the value of the URL field of the client.
Beware that using a client name that contains spaces or special characters might cause problems when an user tries to login!
