Generate Secure Passwords Instantly
PassForge creates strong, unpredictable passwords and passphrases using your browser's cryptographically secure random number generator -- free, private, and with no sign-up required.
Password Generator
Your password
This field is fully editable -- click in, then type, paste, or modify the password to check its strength.
Checked locally in your browser -- never sent or stored.
Generate Multiple Passwords
Uses the character options selected above. Generate up to 100 unique passwords at once and export them.
Passphrase Generator
Combines random dictionary words for a passphrase that's easier to remember and type.
Pronounceable Password
Alternates consonants and vowels so the result is easier to read and say aloud.

Built for security, privacy, and speed
Every feature is designed around one goal: helping you create passwords that are genuinely hard to crack.
Cryptographically secure
Powered by the Web Crypto API's getRandomValues() -- never Math.random() -- for genuinely unpredictable passwords.
Zero data collection
No accounts, no analytics, no cookies, no server. Your passwords are generated locally and never transmitted anywhere.
Fully customizable
Choose length, character types, and exclude similar or ambiguous characters to fit any site's password rules.
Instant strength analysis
See entropy in bits and an estimated crack time the moment you generate a password, so you know exactly how strong it is.
Passphrases & pronounceable options
Generate memorable multi-word passphrases or pronounceable passwords when you need something easier to type or say aloud.
Works offline
Install PassForge as an app and keep generating secure passwords even without an internet connection.
Frequently asked questions
Yes. PassForge is completely free, with no sign-up, no premium tier, and no limits on how many passwords you can generate.
No. PassForge runs entirely in your browser. Passwords are generated on your device and are never transmitted to a server, stored in a database, or saved anywhere -- not even in your browser's local storage.
PassForge uses the Web Crypto API (window.crypto.getRandomValues), a cryptographically secure random number generator built into every modern browser. It never uses Math.random(), which is not secure enough for generating passwords.
A strong password is long, unpredictable, and drawn from a large character set (uppercase, lowercase, numbers, and symbols). PassForge measures this with entropy, expressed in bits, and estimates how long it would take an attacker to crack it.
A password is a short, random string of characters, while a passphrase is a sequence of random dictionary words. Passphrases are often easier to remember and type while still providing strong security, because their strength comes from combining many possible words rather than complex characters.
We recommend at least 16 characters for most accounts, and 20 or more for highly sensitive accounts like email and password managers. PassForge supports lengths from 8 to 128 characters.
No. Every account should have a unique password. If one site is breached and you reuse passwords, attackers can use that same password to break into your other accounts -- a technique called credential stuffing. Use a password manager to store unique passwords safely.
Yes. PassForge can be installed as a Progressive Web App and works offline once loaded, since all password generation happens locally on your device with no network connection required.
About PassForge
PassForge was built with a simple belief: the tools that protect your online security shouldn't come with trade-offs to your privacy. Password generators, of all things, need to be trustworthy -- so we designed PassForge to run entirely in your browser, with no backend server, no database, and no third-party scripts involved in generating your passwords.
How it works
Every password, passphrase, and pronounceable password you generate is created locally on your
device using the Web Crypto API (window.crypto.getRandomValues()),
the same cryptographically secure randomness source used by security-critical applications. We
never use Math.random(), which is predictable and unsuitable for generating secrets.
When you select character types (uppercase, lowercase, numbers, symbols), PassForge guarantees at least one character from each selected type while filling the rest of the password from a securely shuffled combined pool -- so your passwords are both compliant with common site rules and statistically unbiased.
Our mission
We want to make strong, unique passwords the easy default for everyone -- not just security professionals. That means keeping PassForge fast, free, accessible, and honest about exactly what it does (and doesn't do) with your data.
Privacy Policy
Last updated: July 7, 2026
PassForge is designed around a simple privacy principle: we don't collect what we don't need -- and for a password generator, that means we don't need to collect anything at all.
What we don't do
- We do not send generated passwords, passphrases, or any options you choose to any server.
- We do not use cookies, analytics scripts, or third-party trackers.
- We do not require or support account creation, so we hold no personal data, email addresses, or profiles.
- We do not store generated passwords in local storage, session storage, or any browser database.
What we do store locally
The only piece of information PassForge saves is your light/dark theme preference,
stored using your browser's localStorage so the site remembers your choice on your next
visit. This preference never leaves your device and contains no personal or password-related data.
Third-party hosting
If you access PassForge via a web host or CDN, that provider may log standard, anonymized web server access data (such as IP address and browser type) as part of normal infrastructure operation. PassForge itself has no visibility into or control over such logs, and does not add any additional tracking on top of them.
Changes to this policy
If this policy ever changes, the "last updated" date above will reflect it. Because PassForge has no user accounts, we have no way to email you updates -- so please check back if you'd like to review it.
