The "randomness" is one characteristic, the other is the length. My passwords' randomness is enough due to certain things, which is used in the pw generation - which is not revealed here either
And length I certainly have enough.
Bottom line: Look at top of this page (bitcointalk.org). The connection is encrypted. How does that encryption work? The encryption key is exchanged between your computer and BTT server using cryptography that relies on random number generator. Otherwise your BTT password would go through internet (bouncing around dozens of servers) in plain text and could be easily stolen, along with your nem stake.
you already rely on CSPRNG to do everything online that is supposed to be secure. Nothing online is secure without CSPRNG.
Not a single thing.
Cryptocurrencies, decentralization, lower trust level ...
pw manager, centralization, higher trust level.
(ok, ofc some centralization and trust is needed somewhere sometimes, but ...)
You already trust a lot of things -- for example your operating system. How do you know it's not sending your info to NSA?'
There is no such thing as zero trust.
With Lastpass encryption is done locally on your computer. They only get encrypted blob. Key is derived from thousands of hashes (PBKDF2) so even in very
unlikely scenario their server is hacked brute force attack would still be very hard, as their server doesn't have encryption key.
It's a question of convenience and security and it's much easier to stay secure if a user is using password manager (online backup, long random unique passwords for all sites, two factor authentication, auto fils and several other anti-key logger measures) .
