Short answer
Open Account in Factuur Simpel and click Set up next to two-step verification. Scan the QR code with an authenticator app, such as Google Authenticator, Microsoft Authenticator or your password manager, and enter the 6-digit code. Then save your 10 backup codes: they sign you in if you lose your phone. Two-step verification works on every plan at no extra cost.
With two-step verification, signing in to Factuur Simpel with your password also asks for a code from an authenticator app on your phone. If someone gets hold of your password, that alone is not enough to reach your invoices and customer details. This guide shows how to set it up, what to do with your backup codes and what to do when you get a new phone.
What is two-step verification?
You sign in with something you know, your password, and something you have, your phone. An authenticator app on that phone creates a new 6-digit code every 30 seconds. Factuur Simpel asks for that code after you enter your password.
Two-step verification is optional: you turn it on yourself. After you sign in, Factuur Simpel suggests it now and then. If you choose Not now, you are asked again later.
Set up two-step verification
After these steps, Factuur Simpel asks for a code when you sign in with your email address and password, on the website and in the app.
- Using the Factuur Simpel app on a phone or tablet? Update it first: older versions can’t ask for the code when you sign in.
- Open Account in the menu under your profile and click Set up next to two-step verification.
- Open an authenticator app on your phone, such as Google Authenticator, Microsoft Authenticator or the authenticator in your password manager.
- Add an account in the app and scan the QR code, or type in the key below it. Setting it up on the phone itself? Use the Open in authenticator app button instead.
- Enter the 6-digit code the app shows and click Confirm.
- Download or copy your backup codes and keep them somewhere safe.
Signing in with a code
After your password, Factuur Simpel asks for your code. Open your authenticator app and enter the code listed under Factuur Simpel.
Code not accepted? Enter the newest code, as each code only works for a short time. If it keeps failing, check that your phone sets its time automatically: the codes depend on the correct time.
Backup codes: when you lose your phone
When you set it up, you get 10 backup codes. Each code signs you in once without the authenticator app.
- Keep the codes somewhere other than your phone, such as your password manager or a downloaded file in a safe place.
- Signing in without your phone? On the code screen, choose Choose another method. Type in a backup code or upload your backup code file.
- After signing in with a backup code, you set up the authenticator app on your new phone. You then get new backup codes.
- Your Account page shows how many codes you have left. New codes creates a fresh set; your old codes then stop working.
- After too many wrong backup codes, you have to wait an hour before you can try again.
A new phone or another authenticator app
Many authenticator apps move your codes to a new phone themselves, through a backup or sync. You then don’t need to change anything in Factuur Simpel.
Want to switch apps and still have your old phone? Open Account and click Set up again next to two-step verification. Scan the new QR code with your new app. The codes from your old app then stop working; your backup codes stay valid.
Lost your phone? Sign in with a backup code. Lost your backup codes as well? Contact us. We check that it’s you and then reset your two-step verification.
Signing in with Google, Apple or Facebook
If you sign in with Google, Apple or Facebook, that service takes care of the extra step, so turn on two-step verification there. If you have also set a password in Factuur Simpel, you can set up two-step verification for signing in with that password.
Authenticator app or password manager?
Password managers such as 1Password and Bitwarden can scan the QR code too. They store the code next to your password and fill it in when you sign in. That is convenient, but it keeps password and code in one place, so protect your password manager with a strong master password and with two-step verification.
