Regaining Access to Your University Account
⚠️ Incorrect User ID or Password / Account Locked
Cause: You may have mistyped your login ID or password, or entered an incorrect password consecutively, leading to a temporary lock. Other devices trying to log in with an old password can also cause intermittent locking.
Solution: Double-check your Login ID and OnePass Password. If locked, wait for 10 minutes before trying again. If you suspect other devices, clear saved login information on them. If the issue persists, contact ITSC Service Desk at 3943 8845.
⚠️ Cannot Receive DUO Push Notification
Cause: Issues with your DUO mobile app or network connectivity can prevent push messages from arriving.
Solution: Ensure your mobile device has an active internet connection. If the push doesn't arrive, you can opt to use a passcode generated by your DUO app to verify your identity.
⚠️ Login Page Errors / Intermittent Issues
Cause: Browser cache, cookies, or outdated login information can interfere with the authentication process.
Solution: Clear your web browser's cookies and cache, then restart the browser. Alternatively, try logging in using an incognito/in-private window to bypass stored data. If the problem persists, contact ITSC.
⚠️ Applications keep prompting for login (e.g., after changing OnePass)
Cause: Saved credentials in your operating system's credential manager might be outdated.
Solution: Clear the Windows Credential Manager to remove old login information.
