Is EFTPS (Electronic Federal Tax Payment System) secure?

Yes. For you to use EFTPS - Direct, you will receive a Personal Identification Number (PIN). Your PIN must be used in combination with your Taxpayer Identification Number (TIN) to gain access to EFTPS by Internet, PC software, or phone. You have complete and exclusive control over your PIN. The government does not have access to your PIN. If you use EFTPS Online, you will also be issued a password that together with your PIN and TIN gives you maximum security online. Make sure your password is secure.
