First of all, it was a good and motivating article. However, as a security paranoid (well, I try to be, that is) I must disagree completely with the original thesis. Any alternative to passwords so far (at least popular and well-known) is a mess (really). Biometrics are literally awful (even a child can crack those). As for emails, this whole idea of many passwords and not using the same one everywhere is correct… So how come you can possibly think of using the same email? I use a dozen of those. And they are all not connected. And every single one has a different password, so it turns out that I need to use different passwords. “What if you use one email?” — you ask. And how is that different from using one password everywhere? That is a dumb way of logging in, because your security bases upon that very same one single password EVERYWHERE, so it it no better in any way. Your mail gets hacked — all your life gets hacked. Therefore, you need to use a couple of them. Well then. You neeed passwords — to log in to all of those accounts. So using emails is the same as using passwords only with one more absolutely unneeded layer, which could also be compromised (so I must say there are some websites that do not have email password reset — and I love those, because they are more secure). Also, people mentioned Keepass here. In my opinion, (though I have no problem at all remembering all of the passwords and do not use it myself) it is a great tool if you cannot (and there is almost no possibility of password theft if used correctly). As for installing it on devises you do not own (which you mentioned as one of the problems for awful proprietary LastPass) — it is a bad idea to log in to websites from them at all — it is bad for security and you totally should try avoiding it. Staying logged in somewhere is not a good idea, as well. As for convenience, I can type all of my passwords (and there are dozens of them) in matter of 5 seconds. As for reading an email — opening a tab with it (or an app), logging in, opening the new message, reading it, opening the link (and waiting while all of it loads) — it takes time (and for me it is painfully long, inconvenient and wasted time). Therefore, I disagree: passwords are not simply the only way so far — they are also the most secure and convenient. And yes, all of my passwords are long and complicated enough (about 9–12 characters (with numbers and punctuation) each — and that is only where I am not afraid to be hacked). I love passwords and I do not agree that there is any possibility not to use them in any future.
