A password generator is a tool or software that creates a random and secure password for users. It generates a combination of letters, numbers, and symbols, making it difficult for hackers to guess or crack the password. The generated passwords are often long, complex, and unique, which makes them more secure than using common words or simple phrases. Password generators can be useful for people who have trouble coming up with secure passwords, or for those who need to generate multiple passwords for various accounts. Some password generators also offer additional features such as the ability to specify the length and complexity of the password, or to generate pronounceable passwords that are easier to remember.
