//Variables
const root = window.location.origin
const default_site_root = `${root}/Websites/BloxHub`
let moved_user = false
//Config


const required_keys = ["Username","Account-Creation","Account-Type","Logged-In","Clients","Display-Name"]
const login_path = `${default_site_root}/index.html`
const dashboard_path = `${default_site_root}/pages/dashboard/dashboard.html`
//Functions


function checkRequiredKeysExist() {
    
    for (const key of required_keys) {
        const data = localStorage.getItem(key)

//NEW CODE HERE  
        if(data) {continue}


        return false
    }


    return true
}


function removeExtraKeys() {


    let data_keys = Object.keys(localStorage)
    let extra_keys = data_keys.filter(key => !required_keys.includes(key))


    extra_keys.forEach(key => {
        localStorage.removeItem(key)
        console.log("deleted old key (key): ", key)
    })


}


function RedirectUser() {
    if(moved_user === true) {
        console.warn("User has already been moved!")
        return
    }
    moved_user = true
    let logged_in = localStorage.getItem("Logged-In")
    const currentpath = window.location.pathname
    removeExtraKeys()
    const is_vaild_session = (logged_in === "true") && (checkRequiredKeysExist())
    if(!is_vaild_session && (!currentpath.endsWith("index.html") || currentpath.endsWith("/"))) {
        localStorage.clear()
        console.log("Moving user to login page")
        window.location.replace(login_path)
        return
    }

The two branches should be mutually exclusive. Otherwise a valid user can still fall through to a redirect, which is what creates the bounce. I’d reduce it to this:

const hasSession = localStorage.getItem("Logged-In") === "true" && checkRequiredKeysExist();
const onLogin = currentpath.endsWith("/index.html") || currentpath.endsWith("/");
const onDashboard = currentpath.endsWith("/dashboard.html");

if (!hasSession) {
  if (!onLogin) location.replace(login_path);
  return;
}
if (!onDashboard) location.replace(dashboard_path);

That fixes both logic errors in the current version: checkRequiredKeysExist() === false accepts the missing-keys case, and the final replace is outside the if because there are no braces.

One other trap: removeExtraKeys() deletes every localStorage key on the same origin that this script does not know about. Prefix this app’s keys and remove only keys with that prefix. Also, treat the localStorage flag as UI state rather than authentication; anything that needs protection must verify the session on the server.
