# Sign in to the Vendor Access Portal

The Vendor Access Portal uses passwordless authentication. To sign in, enter your email address. The portal sends a single-use code to that address, which you enter to complete sign-in.

## Requirements

- The portal address, provided by the customer's administrator.
- An approved registration. To register, see [Register as a third party on the Vendor Access Portal](/v4-2/docs/domum-vendor-portal-register-as-a-third-party).
- Access to the channel that delivers your sign-in code. Your first code arrives by email or SMS, on the channel the customer configured. Later codes come from your authenticator app.

## Steps

1. Open the portal address.
2. On the **Sign in** card, in **Email**, enter the address you registered with, and then select **Continue**.
3. Retrieve the sign-in code. On your first sign-in, the code arrives by email or SMS. On later sign-ins, use the code your authenticator app shows.
4. On **Enter your code**, type the code and select **Verify**. The screen states how long the code stays valid, and offers **Resend code** if it expires.
5. On your first sign-in, register an authenticator app. The portal requires it before you can continue. Later sign-ins use the code from that app.

Info

If you registered but cannot sign in, your registration is probably still waiting for approval. The portal does not distinguish between a registration that is pending, one that was rejected, and an address that was never registered. It returns the same message for all three. Contact the customer who gave you the portal address.

## Verify your results

The resource catalog opens. You see the resources your organization can request and the requests you have already submitted.

Next, request access to a resource. See [Request access on the Vendor Access Portal](/v4-2/docs/domum-request-access-on-the-vendor-access-portal).
