Resolving Common Login Issues & Account Lockouts

⚠️ Invalid Credentials or Account Locked Out

Cause: This typically occurs after multiple failed login attempts, indicating an incorrect username or password, or a security lockout.

Solution: First, double-check your Employee ID or Corporate Email for typos. If you suspect a forgotten password, use the 'Forgot Password' or 'Reset Password' link on the login page. If your account is locked, wait for the specified lockout period (usually 15-30 minutes) or contact the IT Help Desk for immediate unlocking.

⚠️ Multi-Factor Authentication (MFA) Code Not Working

Cause: Common causes include an expired code, incorrect time synchronization on your authenticator device, or issues with SMS delivery.

Solution: Ensure your authenticator app is synchronized with network time. If using SMS, check your mobile device's signal and spam folder. Try regenerating a new code or requesting a resend of the SMS. If issues persist, contact IT support to reset your MFA.

⚠️ Browser Compatibility or Session Errors

Cause: Outdated browser versions, conflicting browser extensions, or corrupted cookies can prevent proper portal access.

Solution: Clear your browser's cache and cookies, then restart the browser. Ensure your browser is updated to the latest version. If the problem continues, try accessing the portal using a different supported browser or in an incognito/private browsing window to rule out extension conflicts.
