Login Issues

This section covers issues related to logging into the Lightspeed Pay app.

I am unable to log into Lightspeed Pay.

If you receive an error when logging into Lightspeed Pay, make sure you have BackOffice access, check that your login details are entered correctly in Lightspeed Pay, and try again.

  1. Ask the Business Owner or an employee with relevant permissions to check if you have BackOffice access.

    Cashiers and Register Managers must have a valid BackOffice login and cannot use a register code to log in. To prevent employees from accessing most BackOffice features while still being able to use Lightspeed Pay, assign them the ‘Receive Inventory’ role or uncheck all boxes on the ‘Permission List’.

    For help managing employee permissions, visit the Manage Staff article.

  2. Re-enter the store name.

    The store name is one word, lowercase, and contains no spaces.

  3. Re-enter the email address.
    • For Business Owners, this is the email originally used to create the Lightspeed Retail account.
    • Other BackOffice users must provide the ‘Login Email’ entered for them in the Staff List.
  4. Re-enter the password.

    The password is case-sensitive and should be entered the same as when signing into BackOffice. Can’t remember your password? Follow the steps here to reset it.

  5. Tap 'Sign In'.

I need to log out of Lightspeed Pay

Logging out of the Lightspeed Pay app is not currently supported, but you can delete the app if it is no longer needed or reinstall the app to allow a different employee to use Lightspeed Pay on the same device.

  1. In Lightspeed Pay, open the Main Menu, tap 'System Diagnostics', and make sure there are 0 items in the 'Pending/Delayed Queue'.

    If there are more than 0 items, follow the steps here to troubleshoot the pending/delayed queue before completing the next step. Failure to resolve the queue will result in data loss after completing step 2.

  2. Follow the steps here to delete the Lightspeed Pay app.

    Failure to complete step 1 may result in data loss after completing this step.

  3. (Optional) Redownload Lightspeed Pay from the Apple App Store, and log in.

‘Card declined’ and ‘Decline’ both mean the attempted charge was refused by the customer’s bank.
