A strong password is a carefully designed secret code that provides powerful protection
against cyber threats.

In cybersecurity, the strength of a password is measured by its complexity, length, and
unpredictability.
Cyber attackers use different techniques, such as Brute Force Attack, Dictionary Attack, Social
engineering-based guessing, Keylogging, etc. to guess or crack passwords.

Modern password security involves creating strong passwords, adding extra layers of
verification, and applying smart tools that detect suspicious login attempts.

A password manager protects password data using strong encryption algorithms, meaning
even if someone gains access to a device, they cannot read the stored passwords.
A passphrase is a type of password that resembles a short sentence or meaningful phrase.

The passwords used today, even the strong ones, require effort to create, remember, and
type.
