Which of the following is a standard online banking protection measure?

• A. Passwords and PINs
• B. Public sharing of credentials
• C. Ignoring notifications
• D. Using the same password for all sites

Answer: (A)

Protecting online banking relies on controlling who can access your account, which hinges on verifying your identity. Passwords and PINs are a standard protection measure because they serve as the gatekeeper: when you enter the correct password or PIN, the system knows it’s you. A strong, unique password and a unused, separate PIN for banking help keep attackers out, especially when you keep them confidential and avoid reuse across sites. Additional security like multi-factor authentication can further strengthen protection, but the fundamental safeguard is having solid credentials.

Public sharing of credentials completely defeats protection because anyone who gains access to them can log in. Ignoring security notifications means you might miss signs of unauthorized access or other threats. Using the same password for all sites makes a single breach dangerous, since attackers could access multiple accounts, including your bank. Because of these reasons, passwords and PINs are the standard protective measure for online banking.
