TreasuryDirect is preparing to move account access to ID.me, according to an official TreasuryDirect notice included in the provided item. The service says the new login process is intended to strengthen identity verification and account security for people managing TreasuryDirect accounts and securities online. The transition has two dated milestones. Starting September 13, 2026, TreasuryDirect users can begin using ID.me to log in. Starting October 28, 2026, TreasuryDirect says ID.me will be required and will replace the current traditional TreasuryDirect login. TreasuryDirect describes ID.me as a government-verified identity provider that uses identity-proofing to verify access. The notice says the added verification is meant to provide assurance that only the account holder can manage TreasuryDirect accounts, securities, and related personal or financial information. The notice also says ID.me is used by other federal agencies, allowing people to access multiple government services without maintaining separate accounts for each one. TreasuryDirect does not list the other agencies in the provided text, so the scope of that cross-agency access is not specified here. For now, TreasuryDirect says users do not need to take action. It says additional information, including required actions and key dates, will be provided before the transition begins. The notice points users to ID.me’s help center and TreasuryDirect’s ID.me FAQ page for more information. TreasuryDirect also includes a phishing warning in the notice. It says the Treasury Department does not send unsolicited emails asking for personal or financial information or demanding fees to release funds, and it tells users to confirm they are on treasurydirect.gov and logged into the TreasuryDirect system before entering or changing information. Who benefits: Users who already have or can create an ID.me credential may get a more consistent login path across participating government services, according to TreasuryDirect. TreasuryDirect also frames the change as a security and identity-assurance upgrade. Who's exposed: TreasuryDirect users who rely on the current traditional login will need to complete the new process before ID.me becomes mandatory. The notice does not describe exceptions or alternative login paths in the provided text.
