*L+<6MokQ5b,V-{.This password generator builds random passwords from the character sets you choose, letting you control length and which character types appear. Toggle uppercase letters, lowercase letters, digits, and symbols, set the length, and request several passwords at once. Longer passwords drawn from larger character sets are harder to guess or brute-force, which is why the tool rates each result by length.
How it works
- Set the desired password length and how many passwords to generate.
- Choose which character types to include: uppercase (A-Z), lowercase (a-z), numbers (0-9), and symbols (!@#$%^&* and similar). If none are selected, the generator falls back to lowercase letters.
- For each password, characters are picked at random from the combined character set until the chosen length is reached, and a strength label is assigned based on length.
Worked example
Generate one 16-character password using all four character types.
- Enable uppercase, lowercase, numbers, and symbols to build a character pool of roughly 84 characters.
- Set length to 16 and count to 1.
- Each of the 16 positions is filled by a random pick from the pool.
A 16-character mixed password rated "Very Strong" (the label is "Very Strong" at 16+ characters).
Frequently asked questions
- How is the strength label determined?
- Strength is based on length alone: under 8 characters is "Weak", 8 to 11 is "Fair", 12 to 15 is "Strong", and 16 or more is "Very Strong". Including more character types also raises real-world security even though the label tracks length.
- What character types can I include?
- You can mix uppercase letters, lowercase letters, digits, and a set of common symbols (!@#$%^&*()_+-=[]{}|;:,.<>?). Turning on more types enlarges the pool each character is drawn from.
- How long should my password be?
- For most accounts aim for at least 12 to 16 characters drawn from several character types. Longer is stronger because every extra character multiplies the number of possible combinations an attacker must try.
- Are the generated passwords stored anywhere?
- No. Passwords are generated in your browser and are not saved or transmitted by the calculator. Copy the one you want into your password manager and the rest disappear when you regenerate or leave the page.
