I've seen so many password tips before, but most involve DANGEROUSLY stupid risks: Like changing every week to something random with a mix of upper and lower-case characters, never using the same password twice and never writing it down on paper or PC. That's just ASKING for a password disaster! Forget your email password (VERY likely because you change it every week!) and NEVER get a re-generated forum password back again! You can get almost the same security as never using the same password with none of the bother, and remember it every time.

Anyway, here's some more logical tips which bring nearly the same level of security with NONE of the hassel.

The backwards trick: Who says you can't use your mother's birthday or your phone number for a password? Flip it around backwards and add hyphens and you've got a password no one can just "guess." Always use it this way so you can memorize the backwards version easily. Who says you can't use a word? As long as it doesn't make another word when spelled backwards the dictionary attack will never work! Choose something easily and logically hyphenated/underscored and you've got a password not many brute-force attempts could crack only in a million years. Replace something else like a zero with a letter "O" and you can guarantee it won't be guessed (when backwards).

The context trick:
If someone intercepts your password even once and you've been using your easy-to-remember password everywhere, they could have your password for every thing you do online. That's why they say to make a different password for every use. How can you do this and maintain your secure and easy to remember password? Add something obvious to it. Add -eb for eBay. Add -pp for PayPal (Or MS Passport but I just use -hm ;)). I'd be pretty easy to get a password from someone who doesn't do this but does use the same password in most cases: Just send them an email, message or make a post which you know interests them where it requires them to make a new password to continue. Either be the entity that password is created with or intercept that password. Use the context trick to thwart this.

For you own convenience/sanity:
Keep it short and all lower-case with universally supported characters. Don't use hypens like I've been suggesting (For the sake of simplicity), but rather some letter you've chosen to replace it. A hyphen isn't universally accepted in all password forms and neither are underscores. I've seen too many cases where a database has been updated and passwords are suddenly case-sensitive or missing their hyphens (ZSNES forums). You don't want to remember case and hyphen-replacments for each of these strange sites. Also, I think it was Sprint PCS which required more than 5 characters, less than 8, not underscores of hyphens and FORCED you to have both letters and numbers: No phone number backwords, and even a truncated backwards date with context trick ("-pcs") was too long so try to choose something within that sweet-spot (It's too late for me). Also, never fill in any profile data which may hint to your password if word of the context-sensitivity of your password gets out ;)

I'd like to see what kind of combinations you guys currently use... Without revealing too much of course ;) Is anyone already doing this?

I use brand names from things I have on my desk. Long as I keep using Powerex batteries, Ronsonol lighter fluid, and Sanyo remotes I'm safe!

Er, wait.

:p

LOL!

I've always used words with numbers and some werid symbols.

Oh, and if something refuses to accept a space; I've found that ALT + 0160 works over 90% of the time :)

I use it for other things too. Most recently, when registering for "My Nintendo" to get my free Zelda Collector's Edition disc, I ran into a form requireing a username, password and display name where the username and the display name could not match and a space was not allowed. ALT + 0160 fixed that :)

You don't even want to KNOW how I generate and memorize passwords like that.

Your own version of 1337-speak? :) With passwords like that, I doubt you'll ever get a form to accept it! ALT + 0160 generates a character which is illegal for many forms but works on many of the ones I've wanted it to :)

Nope, it's highly mathematical and based off system metrics and biometrics.

It's all straight-ASCII. It works on every form I've ever tried it on.

Yeah, but so is a space character and alot of forms refuse those :(

Yeah, but that also stores your passwords so they can all be hacked together at someone's convenience :)

A bit OT here, but . . .
someone told me once a long time ago that there was technically no such thing as a random number generator.
Is this true, or was it true at one time?

I've used parts of CD keys before... also math equations (e.g. sin^2+cos^2, 1=2pi*d [think fourier transform]). The mathematical stuff is easy to vary (=1, -1=0, and so on).

no its true. Computers can not generate a random number because they hae to compute that numbe. They have to make a calculation and produce it. Thats why you could add in something like time, and then it would be mostly random.

Except at the quantum level, it is true. Supposedly by looking at stuff at the quantum level, you can get randomness, but I don't like the idea very much, and don't know enough physics to understand it entirely.

Intel supposedly cracked this random number dillema a long time ago. Remember?

Hardware Random Number Generation
Everyone has been bugging Intel about their ads that the "Pentium III makes the Internet _come alive!!_" Perhaps, just once, Intel was right. Part of the problem with random number-based encryption schemes of the past is that if a user knew how the random number was generated (and it often didn't take too terribly great an effort to figure it out and record it), they could determine the encryption key and and decrypt the message. Several different fairly solid encryption algorithms have been shot down because it was too easy to figure out how the "random number" was generated and duplicate the number, rendering the encryption useless. However, with a truely hardware-based random number generator, it is nearly impossible to duplicate the number because the variables of the test can't be known and the generator thereby creates a "unpredictable random number." The random number generator uses "the thermal noise of a semiconductor resistor to generate high-quality random and nondeterministic numbers".

Now, when the encryption is used, it is far harder to break, and instead of attacking the algorithm by hitting the weakness of a known "random number," the algorithm must now be attacked via brute force, rendering it much stronger than if the number were generated by software alone. This capability could truly revolutionize e-commerce, making encryption far safer for the end user to entrust with their sensitive data.

It is a true random number generator, a part of the 82802 chip -- see

http://developer.intel.com/design/chipsets/supplier/rng.htm
http://developer.intel.com/design/chipsets/rng/techbrief.htm

The Intel RNG works by digitizing thermal white noise, which means that
the results are truly random. However, the process is not very fast
(thermal noise modulates frequency of a slow clock, which triggers
sampling of a high frequency clock, thus generating random bits at a
fairly leisurly pace). Intel's idea seems to be to provide a truly
random seed for standard pseudorandom number generators, which can run
faster. The benefit is increased security in cryptographic
applications; not faster Monte Carlo simulations.
