What is the difference between a passkey and a password ?

A passkey and a password serve similar purposes but are used in different contexts and have slightly different characteristics:

Passkey:

1. Bluetooth and Wireless Devices: A passkey is often used in the context of Bluetooth or wireless devices for pairing or establishing a secure connection. It's typically a short numeric code or PIN that two devices exchange to authenticate each other. This process ensures that only authorized devices can connect to each other.

2. Length and Complexity: Passkeys tend to be shorter and simpler than passwords, often consisting of just a few digits or characters. For example, a Bluetooth passkey might be a 4-digit PIN like "1234".

3. Limited Use: Passkeys are usually used for specific purposes such as device pairing or connecting to a network. They are not typically used for general access control or authentication like passwords.

Password:

1. General Access Control: Passwords are more commonly used for general access control and authentication purposes, such as unlocking a device, logging into an account, or accessing a secure system.

2. Complexity: Passwords are often longer and more complex than passkeys. They can include a combination of letters, numbers, and special characters to enhance security.

3. Wider Application: Passwords are used across a wide range of contexts, including computers, smartphones, online accounts, banking systems, and more. They play a crucial role in securing digital information and ensuring only authorized users can access it.

In summary, while both passkeys and passwords are used for authentication and security purposes, passkeys are typically shorter and simpler numeric codes used for specific device pairing or network connections, while passwords are more complex and widely used for general access control and authentication across various systems and platforms.
