If your password for foo.com is foo-hunter2-XYZ and your password for bar.com is bar-hunter2-XYZ, you've got problems.

He never said it was. It could be something like etc. Just because it's predictable to him does not mean it's predictable to all. There are ways of keeping predictability while still obscuring it from everyone else.

Assuming you're more clever than whoever is cracking the password is a bad plan.

1Password can sync your passwords through WiFi [1] without going through some cloud service like Dropbox. This is the main reason I use 1Password, and it so far has met my needs. Caveat is apparently it can only sync with a single computer. [1] https://support.1password.com/guides/mac/sync-wi-fi.html

Unfortunately I can't use 1Password at work because it doesn't have a browser client, and I can't install anything I like on my computer (corporate). Sticking to Dashlane for now.

Technically, a 1Password vault contains a "1Password.html" file that essentially loads up a browser interface to your vault. This may or may not meet your needs, depending mostly on whether or not you're cool with carrying around a thumb drive with your password vault on it.

While LastPass seems to be responding well, I find their entire service exceeds my tolerance for risk. If you don't use a password manager, you've got 99 problems, but a centralized store of your credentials for everything that's a huge target by virtue of having thousands of similarly centralized users ain't one. Using a password manager (good idea) and then storing all your passwords on a 3rd party service of which…

You understand that all the passwords/data are encrypted client side and only the encrypted blob is stored in the cloud? This is exactly what users of Keepass et al espouse when they talk of having their 'locally encrypted database' and syncing it over dropbox etc. You, at least, are identifying the benefit of physical security, but if we are to place any trust at all in encryption then we must accept such a scheme (…

And this is exactly the point being missed by much of this discussion.

Protect the db blob with one ridiculously long master password with crazy amount of PKBDF iterations and 2-FA.

But this depends on the alternative. If, instead of using a password manager, uses only one (or even two or three) passwords across all the websites they frequent, then you are still, in effect, trusting numerous third parties to keep your password safe in the cloud--if any one of these sites is compromised, then your password for all (or half, or 1/3rd, etc.) is compromised along with it. I agree with you that an of…

no one that uses password manager would use the same password everywhere in the first place, were they not using password managers. you simply can't even conjure that as an alternative because that's completely out of character for you hypothetical situation.

I dunno, I did. I used the same password everywhere, and then I got a password manager and started generating passwords. Granted, it may have been the case that it was my desire for stronger passwords that drove me to use a password manager, and not vice versa. I honestly don't remember.

That's no different to how LastPass stores your vault on its servers, isn't it? They're just using their own cloud instead of Google's.

There actually might be a difference in favor of LP. LastPass knows, semantically, what encrypted password archives are, and can monitor for statistically unusual traffic related to an attacker downloading them. Google has no no way to know, if 10k people are storing their encrypted keepassx archives in gdrive, and if those 10k archives are accessed in rapid succession, that it's an attack. It's lost in the noise of…

That blade cuts both ways: the keepassx archives would be lost in the noise of all the other files on Google Drive/Dropbox/etc. On Lastpass, you know you're getting password archives. To me: advantage KeePass.

Plug for https://oneshallpass.com. Open source. Your site-specific password is an HMAC; the key is your password and the payload is the site you're logging in to. Works perfectly offline. You can optionally store an encrypted list of the sites you use (and parameters like number of symbols) to the server.

My compromise has been to come up with a password permutation scheme-- I have a long, secure, high-entropy password which I can modify/salt in a way that's predictable (to me) across sites, such that each site's credentials are unique. Obviously this works across all devices, because the scheme is in my head, and it's simple enough to remember. I don't use any password manager, because like OP, that seems like too mu…

The flaw in your scheme lies in the fact that "it's simple enough to remember" ... this would imply that if one were to target you they could likely correlate your credentials across multiple leaked PW databases and guess at your scheme. That of coarse has plenty of assumptions...

Yes, a motivated attacker could figure it out. But before they could do so, they would need my password in plaintext for multiple unrelated accounts of mine, which is hard, requires the attacker to target me specifically, and by that point what is lastpass really going to do for me anyway?

By far the most likely way my gmail account would be hacked is that foo.com's database is leaked/cracked, and the hackers spam the credentials for foo.com at hundreds of other sites and see what sticks. My scheme defeats that. And it's one point of failure versus several.

If your password for foo.com is foo-hunter2-XYZ and your password for bar.com is bar-hunter2-XYZ, you've got problems.

I don't actually see the scenario where this becomes a problem.

If foo.com is compromised and their passwords decrypted, I find it unlikely that the attackers are going figure out your password scheme, go over to bar.com, and start trying out usernames that are similar to yours with the password scheme they think you have, while they are in possession of all the other foo.com passwords and usernames, some of whom probably have the exact same username and password on bar.com.

I've been using basically hunter2_foo for all unimportant passwords for some time and never had a problem.

The only thing I can think of is that if one person was on a mission to destroy my life and they managed to compromise a couple passwords to figure out the scheme, but I don't see that happening in a way that would not allow them to vacuum up a good number of passwords anyway.
