How to Clear Browser Cache for SSO Users (When Switching Accounts or Old SSO Session Persists)

QC One users and administrators using Single Sign-On (SSO) via browser (Portal) or in-app browser (App).

Updated yesterday

Problem

When a user logs in via SSO (e.g., Microsoft Entra/Azure AD, SAML) and then another person tries to log in on the same device/browser with different credentials, the previous SSO session may persist. This can cause:

  • The new user being automatically logged in as the previous user.

  • SSO login screens skipping credential entry.

  • Access or authorization issues.

This is due to browser cache and SSO session cookies not being cleared.

​Solution: Log out of QC One AND Clear Browser Cache/ SSO Session

For Portal (Web Browser)

  1. Log out of QC One Portal

    1. Click your profile icon (right top corner)

    2. Select “Log out.”

  2. Log out from from Microsoft (as you might be still logged in)

    1. Open a (new) browser window

    2. Go to https://login.microsoftonline.com or My Account.

    3. If logged in, please log out to fully clear the SSO session.

  3. Clear Browser Cache according reference below

  4. Close all browser tabs/windows with QC One open.

  5. Try logging in again

For QC One Inspector App (In-App Browser SSO)

  1. Log out via the app settings.

    1. Try logging again. If the app still logs in with the previous SSO user:

      1. Force close the app.

      2. Clear app data/storage (if possible):

      3. On iOS: Delete and reinstall the app

      4. On Android: Go to Settings > Apps > QC One > Storage > Clear Data.

  2. Clear Browser Cache according reference below

  3. Reopen the app and log in with the new SSO user.

Additional Notes

  • SSO session persistence is a known limitation when using shared devices or browsers.

  • For privacy and security, always log out and clear cache/cookies before handing over a device to another user.

Troubleshooting

  • Still seeing the previous user?

    • Try a private/incognito window for the new login.

    • Ensure all browser windows are closed after clearing cache.

    • On shared iPads or kiosk devices, a full device restart may be required.

  • App still remembers old user after logout?

    • Uninstall and reinstall the app to clear all local data.
