When creating a password, the number of symbols that can be used varies depending on the specific requirements of the system or service that you are using. However, in general, a password can include any combination of uppercase and lowercase letters, numbers, and special characters such as punctuation marks, @, #, $, %, etc. For instance, a system may require a password to be at least eight characters in length and include at least one uppercase letter, one lowercase letter, one number, and one special character. It is always recommended to use a mix of characters to create a strong password that is difficult to guess or crack. It is also essential to use unique passwords for each service or account to protect against potential data breaches.
