Passwords function as a security measure by requiring users to input the correct sequence of letters, numbers, and symbols to gain access to accounts or devices. They are typically created by users and should be kept confidential to prevent unauthorized access. Strong passwords often include a mix of upper and lower case letters, numbers, and special characters to increase their complexity and resistance to guessing or brute-force attacks.
Password Example
For example, when a user wants to log into their online banking account, they enter their username and password. If the password matches the one stored in the bank’s secure database, the user is granted access to their account information.
