@Pmalek @bob123 @o_e_l_e_o you guys should share your opinion with Bitwala, the original author.

really don't like some of the material on that page:
Brain wallets
If you’re feeling risky, then you might consider using a brain wallet. Disclaimer: we wouldn’t if we were you.
No, you don't ever do this even if you do feel risky because there are programs out there like brainflayer being ran by hungry thieves across all the possible inputs and
will take any opportunity to wipe your funds. It's not enough to downplay it by saying "we wouldn't if we were you". They don't even mention how insecure they are.
Anyways, it’s harder for a hacker to crack two keys than one and that’s why multi-signature solutions are better to ensure enhanced security. It’s also harder to lose two keys than just one. That’s if you store them separately (of course, both in highly secure locations/multiple highly secure locations). That way, if you lose one, you still have access to your coins.
(I assume this is 1-2 Multisig) Hackers usually don't crack the keys, they
steal them! So having two different keys is completely useless if somebody just needs one to spend.
Two out of three keys are required for Bitcoin transactions to be authorised and for a wallet recovery to be performed.
This is not a hard requirement, any M-N scheme can be used as long as M <= N.
One way to perform a wallet recovery is to go to a GitHub.io hosted page (specified by your wallet client) and enter your backup key/seed phrase.
...
I'm not even going to begin talking about this. And it's right at the beginning.
(Hint: would you enter your credit card number on some random Github.io site, especially considering ANYBODY can create one for free?)
It's too bad they don't have a contact page anywhere because there's some
really nasty technical errors in this article.
