How to Fix COSTAATT Portal Login Errors, Account Lockouts & Password Resets

⚠️ Invalid Username or Password

Cause: This error occurs when the entered username or password does not match the records. Common causes include typos, using an old password, or attempting to log in with a personal email instead of your COSTAATT username.

Solution: Double-check your Username and Password for any typos. Ensure your Caps Lock is off. If you recently changed your password, try the new one. If the issue persists, proceed with the 'Forgot Password' process or contact the IT Help Desk.

⚠️ MFA Verification Failed or Not Receiving Codes

Cause: Multi-Factor Authentication issues can arise from an unregistered device, incorrect phone number, app sync problems, or network connectivity issues preventing code delivery.

Solution: Verify your phone has network connectivity. If using the Microsoft Authenticator app, ensure it's synced and try refreshing it. If receiving SMS codes, check your spam/junk folder. If you've changed your phone or number, contact the IT Help Desk to update your MFA settings.

⚠️ Account Locked Out

Cause: Repeated failed login attempts (typically 3-5 times) will temporarily lock your account as a security measure to prevent unauthorized access.

Solution: Wait for the lockout period to expire (usually 15-30 minutes) and then try logging in again carefully. If you need immediate access, contact the COSTAATT IT Help Desk; they can manually unlock your account.
