If you are locked out of your DHS account because you’ve forgotten your password or accidentally entered it too many times you can remotely unlock it yourself by going to

Select Password Reset from the options and the system will verify you using information that is saved in the system.

If you have an old phone number in the system then you may be unable to verify your account and you’ll have to call OMES to update it and unlock the computer. The phone number to the service desk is 866.521.2444 if the website is down or you have to call.
