Uhm, those tips are clearly meant for people who are storing their coins on online wallets, since you're mentioning 2FA.
I would advise against giving away control of your Bitcoins to any company. It's always better to have your own secure wallet, one that gives you control over your private keys.
Two-factor Authentication isn't a perfect solution, it can also be broken in certain instances.
I also actually only recommend using Google Authenticator, because I think the level of google security is very high and has been trusted. And the most important thing is we have to stay alert all the time because the risk always try some way to attack you.
