What is a Secure Password Generator?
A Secure Password Generator creates random, cryptographically strong passwords to protect your online accounts from unauthorized access. Strong passwords are your first line of defense against brute-force attacks, dictionary attacks, and credential stuffing. By using truly random combinations of letters, numbers, and symbols, you create passwords that are practically impossible for humans or computers to guess.
Password strength is measured in 'entropy'—the amount of randomness or unpredictability in a password. A password with high entropy has many possible combinations, making brute-force attacks unfeasible. For example, an 8-character password using only lowercase letters has about 37 bits of entropy (26^8 combinations), while an 8-character password with uppercase, lowercase, numbers, and symbols has about 52 bits (95^8 combinations). Industry standards recommend at least 70-80 bits of entropy for strong passwords.
The character types you include dramatically affect password strength. Lowercase letters give you 26 options per character, adding uppercase doubles that to 52, including numbers brings it to 62, and adding symbols expands it to approximately 95 possible characters. However, password length is often more important than complexity—a 16-character password with just letters and numbers is generally stronger than a 10-character password with all character types, because exponential growth favors length.
This tool generates passwords using JavaScript's Math.random() function, which provides pseudorandom numbers suitable for most use cases. For maximum security in highly sensitive scenarios, you might prefer a hardware random number generator or dedicated password management software. However, for typical user accounts, the passwords generated here provide excellent protection when combined with other security practices like using unique passwords for each account and enabling two-factor authentication.
1How to Use
- Use the slider to select your desired password length (4-64 characters). We recommend at least 16 characters for strong security.
- Choose how many passwords you want to generate at once (1-50). Multiple passwords are useful when creating accounts for multiple services.
- Toggle the checkboxes to include or exclude Uppercase letters, Lowercase letters, Numbers, and Symbols based on the password requirements of the website or service you're using.
- Click 'Generate Password(s)' to create your random passwords instantly.
- Review the generated passwords in the output panel. Each password is numbered for easy reference.
- Click individual passwords to select them, or use 'Copy All' to copy all generated passwords to your clipboard.
- Save your passwords securely in a password manager—never write them down in plain text or store them insecurely.
