Set the length and sets
Pick a length between 6 and 64 characters and tick the character sets you want. Longer passwords with mixed sets are stronger.

About this tool
About this tool
Password Generator creates random passwords from the browser crypto.getRandomValues source, with length from 6 to 64 characters, optional uppercase, lowercase, numbers, and symbols, and an ambiguous-character filter. It guarantees at least one character from every selected set and can output up to 20 passwords at once. Generation is local, private, and cryptographically random.
Create strong passwords that are hard to guess and easy to manage. Choose the length, decide which character sets to include, and optionally exclude characters that are easy to confuse, such as 0, O, and l. The generator uses the browser secure random number generator, so the passwords are never created on a server and never transmitted.
Built for daily work
- Create a new password for an online account.
- Generate unique passwords for a password manager.
- Produce a strong temporary password for a colleague.
- Create a Wi-Fi or device password that is hard to guess.
How to use this tool
How to use this tool
Filter ambiguous characters
Enable the exclusion option if you will read the password aloud or type it by hand, to avoid confusing 0 with O or 1 with l.
Generate and store safely
Generate one or several passwords, copy the one you need, and save it in a password manager. The tool does not store anything.
Key features
Key features
Secure randomness
Passwords are drawn from crypto.getRandomValues, the same cryptographic source browsers use for encryption.
Every set guaranteed
If you select uppercase, lowercase, numbers, and symbols, the password contains at least one of each, not just a random mix.
Ambiguous character filter
Exclude lookalike characters such as 0, O, 1, l, and I for passwords you will read or type manually.
Batch output
Generate up to 20 passwords at once and pick the one you like.

Limitations and important notes
Limitations and important notes
- A strong password alone does not protect an account; enable two-factor authentication too.
- The tool generates passwords but does not store them, so save your result yourself.
- Site-specific rules such as rejected symbols may require regenerating with fewer sets.
Frequently asked questions
Frequently asked questions
They use crypto.getRandomValues, a cryptographically secure source, not the weaker Math.random function. That makes the passwords suitable for real accounts.
For most accounts, 14 to 20 characters with mixed sets is a strong practical length. Longer is better for master passwords.
No. Generation happens in your browser and nothing is saved, logged, or transmitted.
Save it in a password manager immediately. If you must write it down, keep the note physically secure and destroy it after setup.

Weak passwords are the reason accounts get compromised. The [password generator](tool:password-generator) creates random passwords with real entropy, lets you choose length and character sets, and never sends the result anywhere.
