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

Video tutorial is attached to this article

Overview

Single Sign-On (SSO) lets you access multiple Flash portals with just one email and password.
For security, all seller members who need to add or update ACH / bank information must first set up Multi-Factor Authentication (MFA) before SSO becomes available.

Before You Begin

• Make sure you’ve been approved for access by Digital Support or your account administrator.

• Have an authenticator app ready (e.g., Google Authenticator, Microsoft Authenticator, Authy).

Step 1 – Set Your Password

1. Look for an email with the subject line: “FLASH Temporary Password.”

2. Open the email and follow the link to create your new password.

Tip: Use a strong password you’ll remember.

Step 2 – 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.

Step 3 – 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

Don’t see the SSO option?

• Confirm that MFA enrollment is complete.

• If the issue persists, sign out, refresh your browser, or contact Support.

One-time code not working?

• Ensure your device’s clock is set to automatic. Generate a new code and try again.

Changed devices or lost your authenticator app?

• Use your backup codes or contact Support to reset MFA.

Can’t edit payment settings?

• You may not have the required permissions. Reach out to your account administrator or Support.
