Using Single Sign-On (SSO) with MFA (Multi-Factor Authentication)

How to Access the Seller Console with MFA and Single Sign-On (SSO)

SSO/MFA video tutorial available as an attachment. 

Single Sign-On (SSO) allows you to access multiple Flash portals with a single email address and password.

For security purposes, all seller members who need to add or update ACH / bank information must first set up Multi-Factor Authentication (MFA) before SSO becomes available.

Get Started

1. Make sure you’ve been approved for access by Digital Support or your account administrator.
2. Have an authenticator app ready, such as:
   • Google Authenticator
   • Microsoft Authenticator
   • Authy

Set Your Password

1. Look for an email with the subject line: “FLASH Temporary Password.”
2. Open the email and select Verify Account to create your new password.

            Tip: Choose a strong, memorable password.

Enroll in Multi-Factor Authentication (MFA)

1. Sign in using your email and the new password you just created.
2. When prompted, follow the steps to set up MFA:
   • Open your authenticator app and scan the QR code or enter the code provided.
   • Enter the one-time code from your authenticator app to verify.
   • If backup codes are shown, save them securely for future recovery.

Note: MFA adds a second layer of security to help protect sensitive actions, such as updating ACH information.

Sign In with SSO

Once MFA is set up:

1. Return to the login screen.
2. Select “Sign in with SSO.”
3. Enter your email and approve the MFA prompt (one-time code if prompted).

Everyday Sign-In (After Setup)

• Go to the login page and click “Sign in with SSO.”
• Approve the MFA prompt when asked.
• You’ll be signed in automatically to other supported Flash portals.

Managing Payment Information

After signing in with SSO, users with the correct permissions can navigate to the Seller Console to add or update ACH/bank account information for their seller account or individual locations.

Troubleshooting

Can’t edit payment settings?
