About Password Generator
This tool creates strong random passwords and passphrases. For a random password, choose the length and which characters to use: uppercase, lowercase, numbers and symbols. You can also leave out look-alike characters such as l, 1, O and 0, or characters that cause trouble in some systems. Passphrase mode joins random words with a separator that you choose, which is easier to type and remember.
Passwords are made in your browser using its built-in secure random number generator, and they are not sent to our server or stored. The strength bar is based on entropy, which is a measure of how many guesses an attacker would need, shown in bits. As a rough guide, 80 bits or more is strong against offline guessing. A long random password gets there easily: a 16-character password with all four character types is over 100 bits.
Passphrases need more care. The words come from a list of 256, so each word adds 8 bits, and a six-word phrase is about 48 bits. For something that matters, use eight or more words, or a random password. Use a different password for every account and keep them in a password manager rather than reusing them or writing them in a note.

Frequently asked questions
Is the password stored or sent anywhere?
No. It is created in your browser and is not uploaded or saved.
How long should a password be?
For random passwords with mixed characters, 16 or more is a good choice.
Are passphrases safe?
Yes if they are long enough. With this tool each word adds 8 bits, so use eight or more words for important accounts.
Should I use the same password twice?
No. If one site is breached, a reused password lets attackers into your other accounts.
Do I need a password manager?
It is the easiest way to keep many unique passwords. Use this tool to generate them and the manager to store them.
