# Introduction

There are cases where you may want to take repeated actions on a payroll account. We recognize that asking the user to log in multiple times introduces friction, so we've added the ability to re-access the payroll account without needing the user to re-enter credentials.

_If the user has multi-factor authentication enabled on their account, user action may be required to complete the login step._

# Use cases

• To increase share of wallet, you can incentivize users to increase their direct deposit allocation after an initial direct deposit switch. Users may initially allocate a small amount into the account, but with the right incentives, they may be willing to increase that amount.

• To help with underwriting decisions, you can leverage income and employment data before asking the user to complete a direct deposit switch.

• To reduce fraud, you can match the identity of the payroll account owner against your customer prior to allowing a direct deposit switch.

# Implementation

Enabling this functionality is similar to the way [standard Link tokens](🔗) are created today. When creating the Link token, pass in the `account_id` parameter from a prior [account.added](🔗) webhook event or from the `login` [client side event in Link](🔗). The `account_id` can be preserved and passed in any time you have it for a user.

Taking the 3rd use case above where you match the identity of the payroll account owner against that of your user, you would first create the Link token with `identity` as the required job. Once your customer logs in and the job completes successfully, you will receive both the `accounts.added` and `identity.added` webhooks.

Note: The `end_user_id` is an optional value you provide when creating a Link Token which we'll return in subsequent webhook events. See [User Model](🔗) for more information.

You can then query for `full_name`, `date_of_birth`, and `last_four_ssn` in addition to other fields to determine if the payroll account owner is the same person as your user. For more info, please see the Income & Employment guide [here](🔗).

A webhook event will be sent for indicating success or failure, if you're registered for it.

If performing an On Demand Update re-activated monitoring for an account a [account.monitoring_status.updated](🔗) webhook event will also be sent. You can learn more at [Maintain Account Monitoring](🔗).

Once you have successfully completed the verification, you can create another Link token to initiate the direct deposit switch using the same `account_id`. In doing so, we will attempt to bypass the need for the user to re-enter credentials. Note that there are some cases, eg. where MFA is enabled, where the user will have to take an action to complete login.

Note: it is not necessary to send `end_user_id` when creating Link tokens for On Demand Update requests.
