Two-factor authentication

Two-factor authentication (2FA) is a way of adding additional security on your account. 2FA requires you to enter an extra code when you log in or perform some account-sensitive action (e.g. changing your password). The code is generated from an application on your computer or mobile phone.

When you have 2FA turned on for your account, Close.io will ask you for a 2FA code in the following cases:

  • logging in to Close.io (whether you use the web browser or the desktop app)
  • changing your password
  • changing your account email address
  • disabling 2FA on your account

Setting up 2FA

To enable 2FA for your account you will need an application that manages 2FA codes, such as Google Authenticator, Authy, or 1Password.

Go to your Account settings and click Enable.


The wizard will generate a QR code. 

Dialog with QR code

You need to scan this code with your 2FA application, then type the code your 2FA application shows. Once completed successfully, 2FA will be active on for your account.

Managing / removing 2FA

If you want to disable 2FA for your account, go to your Account settings page again and click the Disable button. Close.io will ask you for both your password and the 2FA code.

If you lose access to your 2FA code generator, contact support@close.io.

You can also see which team members have enabled 2FA for their account by going to the Team & Plans page (under Settings).

Why we don't offer 2FA via SMS

We don't offer 2FA via SMS because using SMS for 2FA is less secure than using an authenticator application, since SMS can be intercepted.
