Because these days, computing power is actively used to 'guess' your password. Some computers try many times and will 'crack' your password eventually. Some computers (or humans) will try and guess your password based on things you might choose, or use passwords obtained from hacks or data-leaks at different websites.
In all cases; it is wise to use a password only once! And make that password very hard to guess! The best password is one that has nothing to do with you. So a 'random' password (a password that consists of random letters, numbers and symbols) is very hard to crack.
A good password is at minimum 12 characters long and consists of random characters. Preferably a combination of letters, numbers and symbols. Such a password is very hard to 'crack'. A good and strong password is impossible to guess and should have no relation to you as a person.
Yes, everywhere! But preferably only use them once! So for each website or system that requires a password, generate a unique / new one. This will keep your data safest.
If, God forbid, your password leaks (data breach in that system), then all your other websites and systems won't also be compromised.
No, the passwords you generate here are actually generated on your own device. We have no idea which passwords you generate or what you use them for. So they're 100% safe and secure to use!
We do recommend creating long passwords with many different characters though. An easy to guess password is often a bad password!
Either use the native password-manager in your browser (the popup you see, asking you to save the password when you entered it), or use Bitwarden, Lastpass or 1password. These are password managers and will keep your passwords (relatively) safe. We say relatively, because these password managers can, theoretically, also get compromised.
If you choose to write down your password, please keep it safe and don't give others access to it. It's probably best not to store passwords in digital files on your computer.
You can can create a good password here on good-password.com! Just use the form at the top to create as many passwords as you need. They are safe and secure as long as you make it enough characters. Try to never use sensitive data inside your passwords, or verbs / words that others can guess. Keep it totally random, that's usually best.
You can use this website! Good-password.com will form a password for you that is secure and incredibly hard to crack, if at all possible. Do keep in mind that you use enough random characters such as lowercase, uppercase, numbers and symbols. The longer, the better! So use at least 12 characters but don't be affraid to use even more.
Two Factor Authentication (2FA) is a way to validate that the user siging in - is actually the person who is allowed to sign in. This is done through a secondary means of 'proving you are you'. So besides your usual password, you (often) also need to enter a code you receive through SMS text message. Or you need to use a code generated by a 2FA-app such as the Google Authenticator. By using this secondary means of logging in, it becomes a lot harder to compromise someones account, because you'd need access to at least 2 seperate systems. Firstly the password, and secondly the mobile phone / device of this person.
