Two-factor authentication strengthens your sign in security by requiring 2 steps to verify your identity: your password and temporary code available only on your mobile at that moment. Two-factor authentication is one of the best ways to protect against remote attacks and other attempts to takeover your accounts.
To turn on two-factor (2 step) authentication for your account go to Settings > My password and security. In the top part of the screen click on the button: "PROTECT MY ACCOUNT".
This will load up QR code unique to your account that will be used to setup your external Time-based One-Time Password (TOTP) application, most commonly installed on your mobile device. By enabling two-factor authentication on your account, each time you want to sign-in, you will be prompted to enter both your password and code generated by TOTP application.
Prior to continuing activation in Salestrekker, please download one of TOTP applications and install them on your mobile (external article here).
(In example bellow Google Authenticator will be used as chosen TOTP mobile app)
Open selected TOTP application on your mobile and select option to scan QR Code / Barcode and use it to scan QR Code you got in Salestrekker screen. This will link up your TOTP app on mobile with your Salestrekker account and it will generate time lapsing codes that you will be using as second step authentication.
Enter digit you have on your mobile device at the moment into Salestrekker screen to finish two-factor authentication activation in Salestrekker as well.
Now your two-factor authentication is switched on. Next time you logout and login you will be asked after submitting your password to type in current six digit code provided on mobile app you paired it with. For this reason no one else can enter your account besides yourself and you are well protected.
In case you lost your device that contained TOTP app, you can select "Lost your two-factor device?" option in bottom-right of login screen, then enter last four digits of mobile phone added in your account Settings to get one time code sent to you via SMS. After login you can change TOTP app and device in Settings (Settings > My password and security > Remove Two-Factor Authentication and then re-activate it again with described steps from this article).
