  • We tend to use the same password everywhere. This is a very bad idea: If someone manages to find your password, he will gain access to all your private data.
  • When using different passwords, we tend to forget them.
  • We tend to choose simple passwords ( easier to remember ), but it also becomes easier for hackers to guess it.
  • We use softwares create, manage, store our passwords, which is a dangerous pratice as piracy is always possible and in case of problem (crash, reinstallation of the OS) you lose all your passwords.

A good password meet the following criterias:
  • Lengthy - more than 8 characters
  • Contain several types of characters - letters, numbers and symbols.

  • Add a few numbers and symbols.

An example:
  • The pen is mightier than the sword
  • Which gives: Tpimtts
  • Adding numbers and symbols : Tpimtts7%3

Choosing a different password for each website


You should never use the same password on several sites.
Using the method explained above, you can create a password out of a phrase related to the site, for example :

  • "Death to spammers" on Gmail. ---> Dts777
