We live in a world where our online IDs are in the hands of the government and banks, and we rely on them to keep it secure. Blockchain IDs on the other hand, put you and you only in control. Therefore, you can store all your passwords and any other personal information on the blockchain, eliminating the need of passwords in everything.
Banks and government cannot keep your ID's and personal information safe because anything can happen and they might get hacked someday and all of the information you sent or given to them be stolen by hackers if their system is breached.
Here take a look at the meaning of blockchain from google.
Blockchain isn't and can't be used to store passwords.
that is not how blockchain or banks or government work! none of them have anything to do with "passwords and personal information"! banks hold and control your money, and governments snoops around in your personal affairs. and blockchain is just a public ledger that holds transaction history protected by cryptography. it is not supposed to hold your passwords or personal information.
That's correct, I think he didn't know what is the purpose of blockchain and its cryptography.
