Although you cannot change your beneficiary participant account number, you can create a customized user ID that is easy for you to remember to log into your account through the TSP website. This customized user ID will not be valid for any other TSP purpose.
To create your user ID, you will first need to log into My Account with your beneficiary participant account number and Web password. Once you have established your user ID, you can change it whenever you wish. If you forget your user ID, you can enter My Account with your beneficiary participant account number and Web password and create a new user ID.
You cannot use your customized user ID on the ThriftLine.
