What type of password is the most secure?

1. Password

2. Passkey

3. PIN

4. Complex Passphrase

The correct answer is: Complex Passphrase

A password in itself is a string of characters used to prove one's identity or to gain access to a system or application. While it is commonly used, a simple password may also be easily cracked by sophisticated computer algorithms, making it less secure compared to other options. A passkey is similar to a password, but it is usually used to open a computer or a device. It is not as secure as a complex passphrase since it is usually shorter and can be easily guessed or cracked. A PIN, or personal identification number, is a numeric code often used for authentication purposes. While it may provide a bit more security than a simple password, it is still not as strong as a complex passphrase, as it is usually shorter and can be compromised if it is a commonly used combination. A complex passphrase, on the other hand, is a unique combination of words, numbers, and special characters
