A strong password is one you can’t guess or crack using a brute force attack. Hackers use computers to try various combinations of letters, numbers, and symbols in search of the right password. Modern computers can crack short passwords consisting of only letters and numbers in seconds.
Strong passwords consist of a combination of uppercase and lowercase letters, numbers and special symbols, such as punctuation. They should be at least 12 characters long.
Overall, here are the main characteristics of a good, secure password:
1 - Is at least 12 characters long. The longer your password is - the better.
2 - Uses uppercase and lowercase letters, numbers and special symbols. Passwords that consist of mixed characters are harder to crack.
3 - Doesn't contain memorable keyboard path, eg QWERTY, 123
Is not based on your personal information eg name or DOB.
Password is unique for each account you have.
Use a password generator
If you don’t have time to come up with your own strong passwords, a password generator is a really quick and easy way to get a unique and strong password.
There is a Password Generator in Microsoft Edge, which you can use it to automatically generate a strong, unique password suggestion each time you need one
