iSupplier FAQs

Multi-factor authentication (MFA) questions:

What is MFA?

MFA adds an extra layer of security to the iSupplier login process by requiring users to verify their identity with two or more pieces of evidence (or “factors”) to prove they are who they say they are.

One factor is something the user knows, such as their username and password combination. Other factors are verification methods that the user has, like the code from an authenticator app on a cell phone. A familiar example of MFA at work is the two factors needed to withdraw money from an ATM. Your ATM card is the “something you have” and your PIN is the “something you know.”

Why am I required to use MFA to log in to iSupplier?

In today’s security landscape, threats are growing increasingly common and more sophisticated. The types of attacks that can cripple businesses and exploit consumers are on the rise. MFA can prevent some of the most common types of attacks. Using usernames and passwords alone does not provide sufficient protection because it’s easy for bad actors to exploit weak or reused passwords.

MFA ties user access to multiple, different types of authentication factors, making it much harder for common threats like phishing attacks or credential stuffing to succeed — which ultimately makes your iSupplier environment safer from unauthorized access by bad actors. For example, even if a user’s password is stolen, the odds are very low that an attacker will also be able to guess or hack the code from a user’s authentication app on their cell phone.

Additionally, DOE cyber requirements mandate Sandia utilizes MFA for external facing services.

Can I turn off MFA for iSupplier?

No, MFA is the standard login process for access to iSupplier and is required to help keep your account secure.

How do I reset my MFA Password?
  1. On the iSupplier sign in page click the Forgot password/new user setup link.
  2. Enter the email address associated to your account(s) and click the Send verification code button.
  3. You will receive an email from Microsoft on behalf of iSupplier with a verification code. Enter the verification code in the textbox and click the Verify code button.
  4. Your email address will be verified. Click the Continue button.
  5. Enter a new password in the New Password and Confirm New Password fields.
  6. Click Continue to save the new password.
  7. Click Return to Login to login with your new password.
