Answer
The authorisation screen appears in the online (web/mobile) app when a third-party integration partner requests access to your Lightning Payroll payroll data. It is part of a secure OAuth authorisation flow and is only shown for integrations that require access to payroll data ÔÇö not for basic identity or sign-in requests.
If you are already signed in
When the screen detects an existing session, it displays a consent card headed Authorise (or Authorise [Partner Name] when the requesting application is identified). The card shows the email address you are currently signed in as and explains that continuing will grant the integration access to that account's payroll data.

You have two options:
- Continue as this account ÔÇö confirms the authorisation and grants the integration access to the payroll data for the account shown. Use this when the displayed account is the one you intend to authorise.
- Use a different account ÔÇö clears the current session and returns you to the sign-in form. Use this if you need to authorise as a different customer account (for example, if you are a bookkeeper setting up an integration on behalf of a client).
If you are not signed in
If there is no existing session, or after selecting Use a different account, the screen shows a sign-in form. Enter the email address and password for the account you want to authorise, then select Sign In. If your account uses two-factor verification, a code will be sent to your registered contact method ÔÇö enter it in the field shown and select Submit to complete the sign-in. Once signed in, the consent card described above will appear for you to confirm.
If you need to start over
If you entered the wrong code during two-factor verification, select Restart to return to the sign-in form and begin again. You can also use Forgot password? if you cannot remember your credentials.
