# Trouble signing in or staying signed in

> Fix problems signing in to Clarus WMS — wrong URL, credentials, or firewall — and unexpected logouts when opening new tabs.

If you're having trouble getting into Clarus WMS, or you're being logged out unexpectedly, work through the steps below.

## Can't sign in

<Steps>
  <Step title="Confirm the correct web address">
    Make sure you are using the **correct URL** to access Clarus WMS. Using an incorrect address will prevent you from logging in.
  </Step>

  <Step title="Verify your login details">
    Double-check that you are entering the **correct username and password**. Pay close attention to typos.
  </Step>

  <Step title="Check firewall settings">
    Your firewall might be **blocking access** to the system. Make sure your Clarus WMS login URL and the Clarus API are **permitted** in your firewall settings. The API to allow is:

    * `https://clarus-api.com`
  </Step>

  <Step title="Contact support">
    If none of the above steps resolve your issue, contact the **Clarus WMS support team** for further help.
  </Step>
</Steps>

<Warning>If you are unsure how to check or adjust firewall settings, contact your IT team for assistance.</Warning>

## Being logged out unexpectedly

If you're logged out when you open new tabs, try these two steps:

<Steps>
  <Step title="Log out of all existing tabs">
    Close all open tabs, log out of any active sessions, then log back in and check whether the issue persists when opening new tabs.
  </Step>

  <Step title="Clear cookies and cache">
    If logging out didn't work, open your browser settings and clear cookies and cache specifically for the Clarus website. Log out completely, then open a new tab and log back in.
  </Step>
</Steps>

<Info>If you're still being logged out after both steps, contact support and the team will investigate further.</Info>

  <Accordion title="Why am I being asked for a code after my password?">
    Your account may have multi-factor authentication (MFA) enabled. After entering your password, you'll be asked for a short code from your authenticator app. See [Multi-Factor Authentication (MFA)](/knowledgebase/security/mfa-overview) for an overview, or [Trouble with multi-factor authentication](/knowledgebase/troubleshooting/mfa-issues) if a code isn't working.
