Two-factor authentication provides additional protection for your account by only letting you log on with an additional verification code generated by a suitable authenticator app or device, such as Google Authenticator. You can download Google Authenticator for Android from Google Play or for the iPhone / iPad from the Apple Appstore. Other apps or devices that implement RFC 6238 can also be used.
If two-factor authentication is optional on your Jiglu system then you can generate a QR code to use with Google Authenticator by going to My Preferences and then choosing the Two-factor authentication option. Once you turn it on and enter your password you will be shown a QR code that you can use with the ‘Scan a barcode’ option in Google Authenticator to add the account. Now each time that you log on you will need to use the verification code that Google Authenticator gives you. If you later want to turn two-factor authentication off then go to the same preferences page.
If two-factor authentication is mandatory on your Jiglu system then you will be given the QR code to use with Google Authenticator the first time that you log on after it was made mandatory If you later want to generate a new QR code, for example if you change mobile phones, then go to My Preferences and choose the Two-factor authentication option.
If you lose access to the app or device used to generate your verification code then you will need to ask a system administrator to clear your two-factor authentication secret key. You will then be able to generate a new code. Unlike with forgetting your password you cannot carry out this process yourself.
