Usernames and passwords are not saved | Firefox Help
In my case I'd made an exception (to *not*, ever, save a password) for the sites that I wanted to save my password for. I thought it had something to do with the HTTP Basic authentication, but nope.

Is saving passwords in Chrome as safe as using LastPass if you leave it signed in? - Information Security Stack Exchange -
The feature we've been talking about helps users. That other one was a misguided attempt at being useful by filling in forms using things you typed on other websites. So imagine an autocomplete assistant like Clippy, but with worse social skills: "I see you're trying to log in to Ebay; I'll just fill in your login from Yahoo and we can see if that works." Yeah, we had funny ideas about security back in the 90's. You can see why putting autocomplete=off into everything even remotely security-related quickly became a bullet-point in site audits.

15.7. secrets — Generate secure random numbers for managing secrets — Python 3.6.0b4 documentation
Generate a ten-character alphanumeric password with at least one lowercase character, at least one uppercase character, and at least three digits:

import string
alphabet = string.ascii_letters + string.digits
while True:
password = ''.join(choice(alphabet) for i in range(10))
if (any(c.islower() for c in password)
and any(c.isupper() for c in password)
and sum(c.isdigit() for c in password) >= 3):

Generate an XKCD-style passphrase:

# On standard Linux systems, use a convenient dictionary file.
# Other platforms may need to provide their own word-list.
with open('/usr/share/dict/words') as f:
words = [word.strip() for word in f]
password = ' '.join(choice(words) for i in range(4))

Anatomy of a hack: How crackers ransack passwords like “qeadzcwrsfxv1331” | Ars Technica
In fact, there's almost nothing preventing crackers from deciphering the hashes. LivingSocial used the SHA1 algorithm, which as mentioned earlier is woefully inadequate for password hashing. He also mentioned that the hashes had been "salted," meaning a unique set of bits had been added to each users' plaintext password before it was hashed. It turns out that this measure did little to mitigate the potential threat. That's because salt is largely a protection against rainbow tables and other types of precomputed attacks, which almost no one ever uses in real-world cracks. The file sizes involved in rainbow attacks are so unwieldy that they fell out of vogue once GPU-based cracking became viable. (LivingSocial later said it's in the process of transitioning to the much more secure bcrypt function.)

Fighting Hackers: Everything You've Been Told About Passwords Is Wrong | Wired Opinion |
Security is not just about strong encryption, good anti-virus software, or techniques like two-factor authentication. It's also about the "fuzzy" things ... involving people. That's where the security game is often won or lost. Just ask Mat Honan.

We – the users – are supposed to be responsible, and are told what to do to stay secure. For example: "Don’t use the same password on different sites." "Use strong passwords." "Give good answers to security questions." But here’s the troublesome equation:

more services used = more passwords needed = more user pain

... which means it only gets harder and harder to follow such advice. Why? Because security and practicality are in conflict.
