When you sign up with Invoice2go, you have the option to sign up with your Google or Apple account, so that you can log in with a single tap each time you open your Invoice2go app.  

Choosing to sign up with your social account will allow for easy account creation and future logins.

To link your Google or Apple account and use it to log in to your Invoice2go account with one tap (or click), choose Continue with Google or Apple. A permissions screen will appear. Verify that you are accessing the correct account, and that you would like to accept.

Once you choose a sign-up option, you will sign in with that same option each time you need to log in to your account.
