Pseudocode for Handling Login Credentials

Overview

The following pseudocode outlines the logic for handling login credentials. It includes steps for gathering user input, validating the input against stored credentials, granting access upon successful validation, and responding to invalid credentials.

Steps

1. Input User Credentials

BEGIN
    DISPLAY "Enter Username: "
    INPUT username
    DISPLAY "Enter Password: "
    INPUT password
END

2. Validate Credentials

BEGIN
    stored_username = "exampleUser"
    stored_password = "examplePass"

    IF username == stored_username AND password == stored_password THEN
        access_granted = TRUE
    ELSE
        access_granted = FALSE
    ENDIF
END

3. Grant or Deny Access

BEGIN
    IF access_granted == TRUE THEN
        DISPLAY "Login Successful. Access Granted."
        // Proceed to the next step in the application
    ELSE
        DISPLAY "Login Failed. Invalid Username or Password."
        // Optionally, allow the user to retry login
    ENDIF
END

Combined Pseudocode

BEGIN
    DISPLAY "Enter Username: "
    INPUT username
    DISPLAY "Enter Password: "
    INPUT password

    stored_username = "exampleUser"
    stored_password = "examplePass"

    IF username == stored_username AND password == stored_password THEN
        access_granted = TRUE
    ELSE
        access_granted = FALSE
    ENDIF

    IF access_granted == TRUE THEN
        DISPLAY "Login Successful. Access Granted."
    ELSE
        DISPLAY "Login Failed. Invalid Username or Password."
    ENDIF
END

Notes

1. Input Handling: Ensure secure handling of user input, especially the password, to avoid exposing sensitive information.
2. Validation Logic: Extend the validation logic to handle more complex scenarios such as password hashing, database queries, and user account status checks (e.g., locked or inactive accounts).
3. Security Considerations: Implement measures to prevent brute force attacks, such as limiting login attempts and using CAPTCHA.
