FAQ

Why would you need a random password generator?

Many people use passwords that are too simple or repetitive, such as birthdays, 123456, or “password,” which are easy to crack. Using a random password generator allows you to quickly create strong and secure passwords, protecting your accounts from being compromised.

What are some common passwords that are easy to guess?

Common and easily guessable passwords include “123456,” “password,” “qwerty,” “111111,” “123123,” as well as combinations based on personal information like birth dates, names, or phone numbers. Such simple or patterned passwords are easily cracked through dictionary attacks or brute force. It’s recommended to use randomly generated passwords that are long enough, include uppercase and lowercase letters, numbers, and special characters, and to securely store them using a password manager.

What password length is considered safe?

It is generally recommended that passwords be at least 12–16 characters long. For important accounts, such as banking or email, 20 characters or more is advised. The longer the password, the exponentially harder it is to crack. This tool supports lengths from 8 to 50 characters, adjustable according to different needs.

How can passwords be safely stored and managed?

It is recommended to use a professional password manager to store passwords, avoiding writing them on paper or saving them in computer files.

How often should passwords be changed?

It is generally recommended to change passwords every 3–6 months, especially for important accounts. If any suspicious activity is detected, the password should be changed immediately.
