Adding and Removing Sign-in Methods

A ReceiptRoller account can have several sign-in methods: email and password, LINE, Google, Microsoft and more. This article explains how to add and remove them, and what happens when a method is already used by another account.

See your sign-in methods

  • Browser: open "Account settings" from the avatar at the top right and look at "Connected accounts". The date each was last used is shown
  • LINE mini app: tap the gear at the top right of Home, open Profile settings, and look at "Sign-in methods"
  • A LINE connected through a store's LINE shows the store's name

Add a sign-in method in a browser

  • In "Connected accounts", choose "Connect" next to the service you want to add
  • Allow access on the service's screen. You return to ReceiptRoller with the method added

If that service account is already used by another ReceiptRoller account, it can't be added. To bring the two accounts together, see Merging accounts.

"An account already exists" when signing in with Google for the first time

You see this when your Google (or other) email address is already registered with ReceiptRoller. No new account is created.

  • Choose to sign in to your existing account, and sign in the usual way
  • On the "Connect Google" screen, choose whether to connect it
  • Once connected, you can also sign in to that account with Google

If you've forgotten your password, reset it first. If you sign in to the existing account within 30 minutes of signing in with Google, Account settings shows "You can connect Google to this account" and you can connect it from there. After 30 minutes, add it from "Connected accounts" instead.

Add an email and password in the LINE mini app

Adding an email and password to an account made in the LINE mini app lets you open the same account in a browser or the phone app.

  • In Profile settings, tap "Add an email and password"
  • Enter your email address and tap "Send a code"
  • Enter the code from the email and a new password, then tap "Save"
  • Passwords need at least 8 characters, including an uppercase letter, a lowercase letter and a number

If another account already uses that email address, you continue to Merging accounts.

Remove a sign-in method

  • In the browser's "Connected accounts", choose "Disconnect" next to the method
  • You can't remove your only sign-in method. Add another one or set a password first

Notices about changes

When a sign-in method is added or removed, we let you know by email and LINE. If you don't recognise a change, see If you get a sign-in or merge notice you don't recognise.
