I just watched the video that you provided. It is very educational and provided me good knowledge about password cracking. I know that we should be very careful in creating passwords and making it very hard to crack is a top priority but I didn't know that with just the use of 4 hi-end Nvidia graphics cards, passwords of million of people can be cracked in just a few seconds. It is an eye-opener for me. I will re-evaluate the status of my passwords because of this video. Thanks man for posting this up. 

The best way is to randomly generate your private keys (paper wallet etc) so that even the owner can not remember. This will not have the problem of having unsecure addresses, like those generated using brainwallet.

No one gonna share their password to anyone. If you do a mistake like keeping hard password and logging in to the site same like blockchain other wallet site means also your funds will be taken out by hackers. Please make proper log in attempt and keep safe private key and don't share your DAT file of tour wallet this enough to be safe.

People don't take the security seriously as they should and that is the reason for so many hacked accounts and wallets, malware infections and other security breaches. But some of them are not well informed how important is to protect your self so this forum could also be the place to raise awarness.

See I don't think you should worry so much.
I insist you to use block chain wallet.
It is damn secure .
I use it mostly in my phone and due to safety reasons,
It doesn't even allow me to take even screenshot,
Of any of the content present in the app.
I.e when the app is open.
Talking about password ,
When I go to settings and select reset password,
They show the message that-
" Our servers have not saved your password"
So even if someone hacks the servers of block chain,
He can never know the password of our wallet.

First of all passwords must be stored in some place no matter what and second bitcoin private keys are entirely different than our websites passwords.
What I want to know is the mechanism where you provide a private key for an address how many times per second could you try a private key to see if it's the right one? if we could limit those attempts somehow that might eliminate the brute force and cracking which depends on try and errors.
I also like the idea of playing music as your password but scientists even doubt if some day human brain might get hacked.

I use cryptocurrencies's addresses as passwords and save each one with a hint of which service it belongs to and put them on a text file then create a zip file with a strong password and cuut and paste it into a usb stick.

Maybe it is true, but not all the people can unlocked those things which are locked, and using password Generator is not that safe also because there is a possibility that you might forgot the password because of too much characters, numbers, signs, and symbols combined.

So, if you are going to use this password generator, you must save your password, for you to have a backup in case that you forgot it. Though, I always prefer creating my own password, for me to easily remember it and can't forget that easily.

account security is a must. but in line with current technological developments, development of how actions are increasingly sophisticated hacking. various ways being developed even though it is a criminal act.

True, 2FA is a must if you want your Bitcoins to be okay, especially on online wallets which can be compromised at any time.  If you have a password and your login isn't going through a device that you've got near you, your safety is slightly compromised.  Good passwords do help but they're not the magic solution to everything.

The way I see it, with all these Vault 7 exploits and backdoors in Cloudflare... no PASSWORD will be safe. You can have the strongest password,

and people will still spoof the site or use key loggers or swap sims to hijack the 2FA. The site should be the strongest point, but it turns out these

sites are the weakest link. Bitcoin used without 3rd parties are still the recommended way to use Bitcoin.
