Password Generator — Create a Strong Password
Generate strong, random passwords with customizable length and character sets.
Strength: Strong
About the Password Generator
A password generator creates a random string of characters that's much harder to guess or crack than a password a person would choose, such as a name, date, or dictionary word. Strong, unique passwords are one of the simplest defenses against account takeover, since attackers can't reuse a leaked password from another site if every account has a different one.
This generator lets you choose the exact length and which character types to include — uppercase letters, lowercase letters, numbers, and symbols — so you can match the requirements of any signup form while keeping the result as random as possible. Generation happens using your browser's cryptographically secure random number source, and nothing is ever sent over the network.
Worked example
Example: setting length to 16 with uppercase, lowercase, numbers, and symbols enabled might produce something like 'qT7$mK2!vB9@xR4h' — a password that would take a modern computer an impractically long time to brute-force, compared to a common password like 'password123'.
Frequently asked questions
- How long should my password be?
- Most security guidelines now recommend at least 12–16 characters. Longer passwords are exponentially harder to brute-force than adding more character types, so length matters more than complexity alone.
- Are these passwords actually random and secure?
- Yes. The generator uses your browser's built-in cryptographically secure random number generator (Web Crypto API), not a predictable pseudo-random function, and everything runs locally — no password is ever transmitted or logged.
- Should I reuse a strong password across sites?
- No. Even a very strong password should be unique per site. If one service is breached, reused passwords let attackers access your other accounts. Use a password manager to store unique generated passwords for every account.
- Why include symbols and numbers?
- Mixing character types increases the total pool of possible characters at each position, which increases the number of guesses an attacker needs to try. Combined with sufficient length, this makes brute-force attacks impractical.
