Fixing Common Login Issues & Account Lockouts

⚠️ Login Failed: Invalid Credentials

Cause: This typically indicates an incorrect username (County email) or password, or a synchronization issue with your network credentials.

Solution: Double-check your typing. If the issue persists, attempt a password reset via the County's password administration tool (if available) or contact the IT Help Desk. Ensure you are not appending '@pwcs.edu' if you are a County Government employee, as this is for Public Schools.

⚠️ MFA/Duo Authentication Failure

Cause: Common causes include a desynchronized Duo app, an unregistered device, or not receiving the push notification/code.

Solution: Ensure your mobile device has network connectivity and the Duo app is open. If you're not receiving push notifications, try generating a passcode from the Duo app. If problems continue, contact the IT Help Desk to reset your MFA settings.

⚠️ Account Lockout

Cause: Multiple failed login attempts will automatically lock your account for security purposes.

Solution: Wait for the lockout period to expire (usually 15-30 minutes) and then attempt to log in again carefully. If you need immediate access, contact the IT Help Desk for an expedited unlock.
