Password

+## Function of a Password

+A password works in conjunction with a [Username](/wiki/username) or other identifier. When a user attempts to log in, they provide their username and password. The system then processes the provided password (often through a hashing algorithm) and compares it with a stored, hashed version of the legitimate password. If they match, access is granted. This process is a core part of [Authentication](/wiki/authentication) and [Identity Management](/wiki/identity_management). Passwords prevent unauthorized access, ensuring that only legitimate users can interact with their accounts and sensitive information.

+## Good Password Practices

+Creating a strong, secure password is vital for protecting digital assets. A good password should ideally embody several key characteristics:

+- **Length:** Aim for a minimum of 12-16 characters. Longer passwords offer significantly more resistance against guessing attacks and brute-force methods.

+A **password** is a secret word or string of characters used to verify a user's identity, serving as a fundamental component of [Authentication](/wiki/authentication). It acts as a digital key, granting or denying access to systems, data, or resources and forming a critical layer of [Security](/wiki/security) in the digital realm.
