A password is a secret word or combination of letters or numbers (a string of characters) used for authenticating a user to give them the right to access information on a computer system. Strong passwords are the ones that are difficult to guess and often require a mix of uppercase, lowercase, numbers and symbols. Strongest passwords require a minimum of 16 characters, however, a password between 8 and 16 characters is said to provide a good level of security. The example of strong password with 9 characters is 21Covid19.
A passphrase is similar to a password in usage, but it is longer and more secure. There are different guidelines to determine the length of a passphrase. Most passphrases have a minimum requirement of 14 characters. A passphrase can be a phrase that the user can easily remember but is difficult to be guessed by others. Passphrases can have upper and lower case characters, blanks and special characters. The example of passphrase is Badaantraugayrang123.
