Get the /sitecore/login page back with ?fbc=1

If you're a sitecore administrator, you may have encountered a situation where the /sitecore/login page is not accessible, and you're unable to log in to the sitecore backend. This can be frustrating, especially if you're not sure what caused the issue or how to fix it. In this article, we'll explore one possible solution to this problem, which involves adding the "fbc=1" parameter to the /sitecore/login url.

What is the "fbc=1" parameter?


The "fbc=1" parameter is a query string parameter that can be added to the /sitecore/login url to reset the forms authentication cookie in sitecore. This cookie is used to authenticate users and allow them to log in to the sitecore backend. If the cookie becomes corrupt or is not set properly, it can prevent users from logging in to the backend.

How to add the "fbc=1" parameter to the /sitecore/login url

to add the "fbc=1" parameter to the /sitecore/login url, follow these steps:

open your web browser and navigate to the /sitecore/login page.
Add "? Fbc=1" to the end of the url, so it looks like this: "/sitecore/login? Fbc=1"
press enter to load the /sitecore/login page with the "fbc=1" parameter.
If adding the "fbc=1" parameter successfully reset the forms authentication cookie, you should now be able to log in to the sitecore backend. If the problem persists, there may be other issues preventing you from logging in, and you may need to try other troubleshooting steps.
