Two Factor Authentication (2FA)​

What is Two Factor Authentication?​

Two Factor Authentication is an option for ScubaBoard members to login with much higher security. It will make it extremely difficult for a hacker to hijack your account without also hacking your phone or email.

Some form of 2FA is increasingly mandatory for online financial services and is an option on many Web sites including Amazon.

Email or App?​

Once you make the decision to use 2FA on ScubaBoard, you need to decide between receiving your auth code by email or with an app on your smart-phone or tablet. Examples of getting your auth code by email can be found below, but you are probably not as familiar with using 2FA apps.

The first thing to note that a cellular or WiFi signal is not required to use a 2FA app, except for the initial installation. Scanning the QR code creates an account in the app and generates new numbers every minute.


This is an example image from the Google Play site. The app regenerates the auth codes every minute.

Notice the 30-second timer icon at the right. It ticks off every second so you can see the time available before the numbers change. The blue icon turns red about 4 seconds before it resets in some apps.

You use the app to scan the QR code on the ScubaBoard screen once, which adds the account to the list. You can rename the account title if needed.

Which App and where do I get it?​

The Apple App Store for iPhones and iPads or Google Play for Android phones. Just search 2FA and screens of free apps are available for download. The two apps that are specifically mentioned in ScubaBoard's 2FA configuration screens are Authy and Google Authenticator, but I have tried one or two others and they work fine.

Step 7: Copy backup codes. It is important to copy these codes and save them in a file. There may be times when you can't use your phone app or receive email and these one-time used codes will get you in.

For security, you may not want to label them some like "2FA emergency backup codes for ScubaBoard". They are just a bunch of numbers to someone else until you give them context.


Step 8, finished: Note that you can disable or change to a different 2FA method (smart-phone app or email) and generate new backup codes on this page.


Step 9, Login: Login to ScubaBoard. Take special note of the "Trust this device for 30 days" checkbox. That is convenient on devices that you use exclusive access to and regularly use to access ScubaBoard.

Enter the auth code number received by email, or the app, an click save.

Authorization Codes & Cookies*​

Re-entering the auth code will be requited:
  • When 30 days pass, if that option was checked in the above screen.
  • When another device is authorized to access ScubaBoard using your account.
  • When ScubaBoard's cookies are not save or deleted. Some people set their browser to delete cookies when exiting for added security.
  • When you change 2FA authorization methods or disable and re-enable it.
* Cookies are small files stored on your device that often includes unique identifiers that web servers send to browsers.
