magic link. That's what medium does for email logins, and slack offers the option as well. it's easily one of the safest methods

Ah.. Yes, but that will leave anyone that has somehow gotten access to my mail to suddenly have access to all my accounts then, wouldn't it?

They already do if they have password reset over email. That's why you need 2FA.

Self hosting is my way to go. Had enough of this. > My wife uses a password manager.

It's not clear to me whether the grandparent is referring to self-hosting password management or file synchronisation. However, one obvious security advantage of self-hosting is that you can use end-to-end encryption (which most cloud sync services don't support).

E.g., I use Resilio Sync (formerly Bittorrent Sync) for file sync with encryption-only keys on my cloud peer. The cloud peer participates in the mesh, providing bandwidth, but if it gets hacked, no one can read the data.

(Of course, I would prefer an open source solution. SyncThing does not have the right sharing model for me. So I was thrilled to hear about LibreVault on HN, which provides functionality similar to BTSync 1.x: https://librevault.com)

Dropbox is about the only service I use a memorable password for, as it has my 1Password file in it, which has my Google one-time-auth codes in it. If I lose my phone while on the road, only remembering my Dropbox password is going to get me out of the mess. Any sensible other solutions here? It's still ~14 characters, but other than making it more random, what are my options?

a subscription service for $3 a month and you get the first 6 months for free. ...and now, a word from our sponsors.

And that puts your data in a (password) silo.

50% of the leaked hashes were bcrypt and the other 50% were salted sha1. So, asking the HNers who crack passwords or follow the tech closely and have a good feel: Salted sha1 can be brute forced much quicker, but in practical terms what kind of complexity of password is vulnerable today if it was stored salted sha1 vs bcrypt? And how can this be projected to change in the next couple of years?

The salts for the sha1 passwords weren't leaked. So they're hard to crack in practical terms. Depends how random they were. See hashcat docs and benchmarks for complete answers to your questions. The GPU versions of hashcat.

I actually googled before asking my question, and couldn't come up with a good feel for just how crackable these are with hashcat... I guess I don't know the terms or the prices.

Is anyone able to make any sense of the GPU hashcat benchmarks that are posted? Something distilled down to "if you spend $xxx, then you can crack any salted sha1 under 12 letters+digits+punctuation in n hours if you knew the salt; if its bcrypt, that would take x hours". Something like that ;)

Added: I'm a bit confused how the attackers know the hash and not the salt though; normally they are stored side-by-side. Or were dropbox using a site-wide salt?

(I've seen systems with a site-wide salt hardcoded into the codebase and a per-user salt in the db with the hash; This means attackers have to compromise both sourcecode and db to get far.)

Keep your password written on a piece of paper in your wallet, with a few extra characters you need to remember to ignore.

Anyone know of automated ways to rotate all the passwords on all of our accounts across the web?

It's a common feature of password managers.

Honest question: Why does any none need password managers? Does not chrome password sync or firefox sync do the job? Thanks

Why not use firefox sync or chrome password sync? All data is locally encrypted before uploading.
