![]() When installing each site, you specify the cookie path, domain and hash method in the wp-config.php file, overriding the default functions. In summary, you install each of your sites into the same database using a different database prefix, remembering not to log in to any of these sites until you complete the entire process. I won’t describe the process in detail here as it’s outlined step-by-step in a Stack Exchange post from 2017. ![]() There is also a caveat in that the sites must be installed on the same domain or sub-domain for this to work. This limits the options you have to improve database performance for a single site. Like a multisite installation, this method requires that your shared WordPress sites all store their information in the same database. It is doable but it isn’t a good overall solution. So, what if we could create multiple WordPress sites that shared common wp_users and wp_usermeta tables? In the previous sections, we have seen that session cookies are bound to a users login details which WordPress stores in the wp_users table in the database. I don’t recommend this method, but I’ll describe it for reference just in case somebody points it out in future comments. WordPress MultisiteĪ multisite operates a bit differently than single WordPress sites and can perform SSO if the administrator of each subsite has the same email address as the network super admin.īut that only works for super admins, not for regular site users.Īgain, we need to find a solution for Single Sign-on even in multisite. Cookie ConclusionĬookies are not transferrable between different WordPress sites, and this is why we need to implement an SSO solution. It is highly recommended that you visit the link in the comments about the SALT keys to generate a new set.Ĭopy and paste the new values into the wp-config.php file replacing the default ones. That’s pretty much everything you edit in WordPress.Īfter you have successfully logged in, the browser stores the cookie wordpress_logged_in_ which indicates when you were logged in, and who you are. This cookie allows access to everything in the /wp-admin/ folder. When you initially log in, the cookie wordpress_ is set to store your login credentials. The browser can read, update and delete cookies using the JavaScript language.Īccording to the WordPress codex, three cookies are stored on your computer to track session information. WordPress stores login session information in three cookies.Ĭookies are small data files stored on your local computer by your web browsers. So we let them log in to our website, accessing the premium content that regular visitors can’t access.Īfter a user logs in, we want them to be able to navigate around our WordPress site or their member dashboard, without having to re-enter their login details on each page refresh.Ī session will usually last until the user logs out, closes all related browser tabs or if the session has been idle for a set amount of time. When users need to do more stuff like edit content, purchase items, checkout or take lessons we want to hold them accountable and to make sure they can only do the things they are allowed to do. Those pages are open to the public, and we’re happy for visitors to read them, and they don’t need any special permissions to do that. Users without a login, customarily called “visitors”, can navigate around the public pages of your website, without having to enter any identifiable information. Here is how to successfully implement WordPress Single Sign-On where users sign in once then get access to multiple sites without having to log in again.īefore we jump into the solutions, we should first understand how users log in to WordPress.įor this post, we are considering two types of user interactions with our website – a non-logged-in user and a logged-in user. We call this Single Sign-On or SSO for short. In essence, they are looking to share login session information across multiple sites. I’m often asked whether it is possible for a user to sign in to a site just once but get access to multiple WordPress sites. When working with large organisations, it is inevitable that they are going to have more than one WordPress website.
