Strong Password Generator
Create strong, random passwords with letters, numbers and symbols. Choose the length, see how strong each one is, and make up to 50 at once.

Very strong · 103 bitsIs it safe?
- Passwords are made on our server with a cryptographically secure random generator, sent to you over HTTPS, and never stored or logged.
- Only your settings (length, character kinds) are in the page address, not the passwords.
- Use a different password for every account, and keep them in a password manager.
- 80 bits or more is very strong: 16 random characters from all four kinds gives about 104 bits.
Password Generator: frequently asked questions
How long should a password be?
At least 12 characters, and 16 or more for important accounts. A 16-character password using all four kinds of character has about 103 bits of entropy, which is very strong.
Is it safe to generate a password online?
These passwords are made with a cryptographically secure random generator, sent over HTTPS, and never stored or logged. Only your settings appear in the page address, not the passwords.
What does "leave out look-alikes" do?
It removes characters that are easy to confuse, such as I, l, 1, O, 0 and o, which helps when you have to type or read the password out.
What is password entropy?
Entropy measures how hard a password is to guess, in bits. Each extra bit doubles the guesses needed. Under 40 bits is weak; 80 or more is very strong.
