2FA A Must!!!
2 Factor Authentication (2FA) / 2 Step Verification is a big push these days and works as an additional security in this ever increasing world of social engineering and cyber threats. Not just at your work but for your personal account as well.
This should be turned on for every app you use if you care about your security. Many big providers have this option like Facebook, Gmail, Twitter, Dropbox, Apple, Microsoft, Crypto Sites etc… The list goes on and becomes larger day by day!!!
Most common additional security are SMS, Phone and App verification (There are additional types but these are most common). Because these are a separate disjoint method if say your email (in the cloud) is compromised and these methods are not affected by the internet to say as such!!!
For App Verification I say u MUST have an app which has a backup and restore functionality. I have over 20 apps on 2FA and imagine if I lost my device / format then I will have to go to each of the 20+ sites, disable 2FA and then re-register for 2FA. PITA (Don’t think I will even remember all the sites until I hit them some random day and it asks for 2FA code!!! Lol!!!)
Therefore, I really recommend a few:
- LastPass Authenticator: Backup and Restore functionality and if you already use Lastpass as a password manager, you already have an account.
- Microsoft Authenticator: Just been updated with backup and restore functionality on iOS a day ago.
- 1Password Authenticator: If you are already invested in this wonderful Password App.. Don’t look any further!!!
- Authy: Strong leader in this field.
I therefore simply can’t recommend Google Authenticator as they don’t have a simple backup and restore facility (and looks so dated). Any app supporting RFC6238 TOTP (Time-Based One-Time Password) and site supporting that is good 🙂
Companies enabling 2FA and allowing QR code scan MUST allow you to use any app which a user wishes to use so that you can use a central repository of your own backup and restore (and ease of use). If you are forced to use proprietary apps for each login (say Google says must use google app, LastPass says must use LastPass auth app, Microsoft says must use their app)… you can imagine the number of apps you will end up with on your phone and to manage them.
The positive of individual apps is that since they are customized for the site, they can do push notifications which allows easy login (via allow/deny or yes/no button popup). But I will still like a single app experience.
Sometimes, its a decision to give the “branding” of the company but I totally disagree with this as 2FA should be seamless for a user and if I have everything controlled by 1 app then why not? Bad business decision (user un-friendly) if they force their own auth app over the more popular ones.
But that is normally not the case with most of the big companies and majority didn’t even bother to write their own app (and thus maintain app and code).
Apps are broken after 2FA???
Once you have 2FA ON (say on Google – I am heavily invested in their online ecosystem like mail, calendar, contacts etc), you will suddenly realise that many apps are asking for your password again. Say, for example, I turned on 2FA on my Gmail and I was using the same to log in and send pics to me (IMAP Protocol) of my security cameras when triggered by my security software. It stopped working. Or my contacts or calendar syncing via CardDAV or CalDAV protocols on my iPhone suddenly starts asking for the password.
This is because these apps can’t handle 2FA as they are not built for that. Google gives you an easy method to circumvent this issue by generating App Passwords for them. It allows you to generate a one time random 16 digit passcode which you can enter it on these apps. You DON’T have to remember them or write them down as if you have to re-enter it on the devices, just generate a new code. You can go here to do so.

Other providers like Microsoft, Yahoo (really? someone using it still?) etc do have a similar method.
TL;DR: 2FA – Turn ON (Not just for your business but for your personal use as well), use an app with secure backup and restore feature for sanity and if some apps suddenly break then look for App Password setting from the provider.
