To know how to enable and use 2FA for your account, please follow the instructions from this article.

Changing or removing 2FA

Removing 2FA

If you need to remove your two factor authentication while you are logged in, you simply jump to Settings > My password and security tab > click on 'Remove the two factor authentication' button.

Changing device

In case you've changed your device and were using the TOTP 2FA option (authentication app), first important step is to remove two factor authentication for your Salestrekker account.

Before switching to a new device, make sure to remove your Salestrekker account from the app on your current device in order to ensure that two-factor authentication (2FA) is set up correctly on the new device.

Once the first step is completed, you can install the authentication app on the new device (recommended: Google Authenticator, download from Play Store or App Store).

Now you can go to Settings > My password and security tab in Salestrekker and reactivate 2FA. Full instructions on that can be found in this article.

Changing mobile number

If your mobile number has changed and you wish to update it in Salestrekker, you need to 'Remove the two factor authentication' first, then update your mobile number in account settings, before eventually reactivating the 2FA.

Please keep in mind that when entering your account mobile number, it must be formatted in this way: 0412345678 < no spaces between digits and with beginning trunk and area code 04.

Lost device

If you have lost your device, or for some other reason you don't have access to it, you will be able to reset 2FA only if you still have access to your mobile phone number.

If you lose your device, immediately contact your mobile provider to cancel existing sim card and ask for new one.

Once you have obtained your phone number again, you can click on 'Lost your two-factor device' on the login screen, which appears after you have entered your username and password.

Next screen will prompt you to enter last 4 digits of your mobile phone number, and you will receive one time code for login via SMS.

Sometimes the first couple of codes received via SMS will behave as invalid when using them to log in.

This is because the SMS codes need to sync to the codes generated in your authentication app.

Attempting the SMS codes a few more times should usually solve the issue.

After you have logged in you can disable 2FA and enable it again while using new mobile device.

If you have lost your mobile device and you can not obtain the same mobile number, please contact your aggregator for resetting the 2FA.
