No unit passwords!
A single password to be used for many purposes is risky. If you take a "unity password" for an easy to "cracking" or someone you use when typing the password observed with the password can be great damage done. Even if it is uncomfortable: use many different passwords! The simpler for chat and communities, the average for online orders, the most challenging for online banking.
not write down passwords!
All these precautions are useless if you store the passwords in an unencrypted file on your PC! On the other hand, no one can remember which of several Matching words he has used for what purpose. You could use a two-tier system:
Write a range of passwords on a piece of paper. If you have half a dozen passwords that will let you know by heart this time. write this note not to what each individual password to use.
letter you use on a different note, what the password for a particular application. This is not immediately clear which passwords are used for what purpose. Write down this list of applications not the passwords, but only the first letter or its length, if all your passwords different lengths (eg, "ebay 8" means: use ebay's existing eight-character password). This password list, you can optionally use stored on the PC, but in a file with an non name. The browser offers to save the password. At least for the more important passwords should you refuse this offer. The file that Windows stores the passwords, is easy to crack.
Internet use at public computers
For PCs in Internet cafes, universities and hotels, you never know how good they are protected. A few vendors put the PC back automatically after each use in the original state. In general, the security measures are unfortunately lacking. Perhaps the user is infected before you the system? Avoid to put your USB drive into a strange computer! You can not know whether the user has left in front of you a keylogger (this is called a background program that secretly recorded passwords). Ebensowenik you can know whether the next user that evaluates you left behind cookies and other data.
Minimize the risk:
let anybody watch while you type in a password
passwords never on other PCs
store the passwords frequently enough change
If the provider allows, use an "anti-keylogger. Such a program prevents keystrokes can be logged. Well suited is the program http://myplanetsoft.com/free/antikeylog.php, which are not installed.
Finally you should delete temporary Internet files, cookies and history.
