Types of passwords you should never use.

A password is a secret combination of characters, typically composed of letters, numbers, and symbols, that grants access to a restricted system, device, or service. 

Passwords are used as a security measure to authenticate and verify the identity of a user before allowing them access to protected resources. They serve as a barrier to unauthorized access and help ensure the privacy and security of sensitive information. 

It's essential to choose strong, unique passwords and to keep them confidential to prevent unauthorized access to accounts or systems.
