Twitter and Password advice
Advice from Twitter in managing your
and password advice
They recommend - 'Use a strong password. Your password should be at least 10 characters that include upper and lower case characters, numbers, and symbols. You should always use a unique password for each website you use; that way, if one account gets compromised, the rest are safe.'
However I don't think 10 is enough 12 is better and for those he find it difficult to remember passwords a pass phrase is helpful such as 'Ilikemy1girlfriend'
That's 15 chars long and you could also use password padding to make it extra hard. so for example '///Ilikemy1girlfriend\\\'
You can also use password vaults such as Keepass when it saves and encrypts your username & password so you only have to remember one.
Hackers don't hack or try one password at a time. They may steal a whole database from a less secure site and at their leisure use software to work out the passwords and if you use the same password for several services they have hit a goldmine.
