Free Password Generator

A password generator picks characters at random from a defined set: letters, digits and symbols. This tool draws that randomness from your browser's Web Crypto API, the same cryptographically secure source used to generate TLS keys, and uses rejection sampling so every character in the set is equally likely. The result has no pattern for an attacker to predict, unlike a password a person invents.

Yes. The Cloudzeta password generator is completely free, requires no account, and has no usage limits.

Yes. The page is static and the generator runs entirely in your browser. No password is transmitted, stored, or logged. You can confirm this by opening your browser's network tab while generating, or by disconnecting from the internet: the tool keeps working offline.

Modern guidance from NIST is to stop rotating passwords on a fixed schedule. Forced expiry pushes people toward predictable variations like Summer2024 then Summer2025. Change a password when you have a reason to: a breach notification, a shared credential, or any suspicion of compromise. A long, unique, randomly generated password can otherwise stay in place.

Reusing one password across sites is the most damaging, because a single breach then unlocks many accounts. Others include building passwords from personal information such as names or birthdays, relying on predictable substitutions like replacing "o" with "0", using short passwords with added complexity instead of longer ones, and sharing credentials over email or chat.

No. Every password is generated locally in your browser using the Web Crypto API. Nothing is transmitted over the network, written to storage, or logged. You can verify this by opening your browser developer tools and watching the network tab while generating passwords, or by disconnecting from the internet entirely: the tool keeps working.

Length and randomness. A strong password is long (16 characters or more), drawn from a large character set, and generated randomly rather than chosen by a person. Predictable substitutions such as replacing "o" with "0" add almost no real security, because attackers test those patterns first.

Entropy measures how many guesses an attacker would need. Each additional bit doubles that number. Below about 45 bits a password is weak against modern hardware; 65 bits is reasonable; above 100 bits is excellent and effectively out of reach of brute force.

Random passwords are shorter and ideal when stored in a password manager. Passphrases are far easier to type and remember, which makes them a good fit for the handful of credentials you must memorise, such as your device login or password manager master password. Both are strong when generated randomly.

Characters such as 0 and O, or 1, l and |, are easy to confuse in many fonts. Excluding them helps when a password must be read aloud, typed manually, or transcribed from a screen. It slightly reduces entropy, so increase the length a little to compensate.

Use a reputable password manager. It lets you keep a unique, long, random password for every account without memorising any of them. Never reuse passwords across services: a breach at one site is the most common way accounts elsewhere get compromised.
