How to create a strong password

Password or passphrase?
A random string packs the most strength into the fewest characters, which suits accounts stored in a password manager. A passphrase of five or more random words is a strong, easy-to-type choice for a master password, Wi-Fi key or device login.
Frequently asked questions
Is this password generator secure?
Yes. PassCreator uses window.crypto.getRandomValues, the cryptographically secure random number generator built into your browser, and avoids modulo bias when picking characters and words. Everything runs locally on your device.
Are passwords stored on a server?
No. Passwords are generated entirely in your browser. They are never sent over the network, logged or stored anywhere.
What makes a password strong?
Length and true randomness. A strong password is at least 14-16 characters, uses a mix of character types, is generated randomly rather than invented by a person, and is unique for every account.
What is a passphrase and when should I use it?
A passphrase is a sequence of randomly chosen words, such as Correct-Horse-Battery-Staple. It is easier to read and type than a random string, which makes it a good fit for master passwords, Wi-Fi keys and device logins.
What does Avoid Ambiguous Characters do?
It removes look-alike characters such as 1, l, I, 0, O and o so a password is easier to read and type correctly.
Should I use a password manager?
Yes. A password manager lets you use a long, unique, random password for every account without memorizing them.
