Vidéo - [Video]: What is a good password on the internet?
Use a different password for each access: if one is hacked, only the service concerned will be vulnerable;
Create passwords that are long and complex enough: a good password must have at least 12 mixed-case characters, numbers, and special characters to stop attacks by computers that test tens of thousands of combinations per second.
Create passwords that you can't guess: Avoid using personal information that's easy to find, like your child's first name, birthday, your favorite music group. Also avoid simple logic suites like 123456, azerty, abcdef... which are among the most common passwords and are the first combinations that cybercriminals will try to force your accounts. For example, choose the first letter of the words in a quote;
Use a secure password manager: it will save your passwords for you and avoid writing them down in an unsecure place. You will only have to remember the one that allows you to open access to it;
Change your password at the slightest suspicion: if you have any doubts about the security of one of your accounts or if a business with whom you have an account has been hacked, change it immediately. Whatever the circumstances, remember to change your passwords regularly;
Never share your password with a third party - no serious organization asks to share it with them by email or phone, even for IT maintenance or troubleshooting;
Never use your passwords on a shared computer (hotels, internet cafes...): they could be recovered by a criminal. If you are forced to use a computer that is not your own, use the browser's private browsing mode, be sure to close your sessions after use and never save your passwords in the browser. Finally, as soon as you regain access to a trusted computer, change any passwords you used on the shared computer as soon as possible.
Enable dual authentication when possible: In addition to your account name and password, these services require you to provide a temporary code that you can receive via SMS on your mobile phone or that can be generated by a specific app or key that you control. With this code, only you can, for example, authorize a new device to connect to protected accounts or authorize a bank transaction;
Change the default passwords of the different services you access: they are often known to cybercriminals. It is important to replace them as soon as possible with your own passwords;
Choose a strong password for your email—it's one of the most important passwords to protect. This is because your email address is typically associated with many of your online accounts. In particular, it allows you to receive password reset links from your other accounts. A cybercriminal who successfully hacks your email could easily use the feature
