# 363.19 What should I do if I become aware that my password or other form of authentication has become compromised?
If you become aware that your password has become compromised, that any other form of authentication has been compromised, lost, stolen, or misused, or that there have been any unauthorized transactions in your account, you may place a hold on your account so that it cannot be accessed by anyone, and you should notify us immediately by e-mail or telephone. Contact information is available on the TreasuryDirect Web site.
