Answer Details
To secure data online, all of the following measures can be used: Password, Encryption, and Personal Identification Number (PIN). These measures help to protect sensitive information from unauthorized access, theft or hacking.
- Passwords are commonly used to restrict access to online accounts, devices or networks by allowing only those who have the correct password to gain access. Passwords are usually a combination of letters, numbers and symbols that are difficult to guess.
- Encryption is the process of converting plain text into a code that is difficult to decipher without the correct key or password. Encrypted data is protected from unauthorized access or tampering.
