Should users use Unicode characters in their passwords to make them harder to crack? Why might this be a good idea... why not?

If you recommend that users use Unicode, please specify how they should accomplish this?

If you recommend that they do not use Unicode, what method would you recommend?

What method do you use for picking and storing passwords?

Solution

Yes users might be used the unicode characters in thier passwords to make them harder.

Yes, this is be a good idea for anybody can do the hacking.

why not means, if the user cannot keep the password like unicode, hackers easily hack the password.

If we use rather than ASCII character or else alpha numeric numbers, password cannot be protected.

because all the users cannot be used unicode compatability scripts.

By extending the possible character set of passwords to include Chinese, Japanese, Korean, Arabic characters, I can increase entropy of the passwords to incredibly high levels without making the password longer or more difficult to remember. In fact it may be easer of my Chinese users to remember a Chinese password than a English language one. It would be very unlikely that someone could brute-force or use a rainbow table to crack the password.
I can understand the Character set limits on western users where the Characters used are all the ones on a keyboard and it is quite awkward to enter a Character that is not on your keyboard. However, Chinese users have to tools on their system to enter the full Chinese character set so there is no problem for them there.

for picking and storing passwords I will recommend the unicode characters only.

Rather than anybody didn\'t know about unicode better to keep alpha numeric characters in critical ways.

rather than user names and common names like that.
