Yes. It uses your browser's cryptographic random number generator, and nothing is sent or stored anywhere.

Yes. Change the length and toggle uppercase, lowercase, numbers, and symbols to fit any site's rules.

A random 20-character password with mixed character types is extremely strong for almost every account.

No. Use a unique password for each account and store them in a reputable password manager.

A random password mixes unrelated letters, numbers and symbols, which gives maximum unpredictability per character. A passphrase strings several random words together, making it longer and easier to type or remember. This generator focuses on truly random character passwords, which pair best with a password manager.

For email, banking and other important accounts, aim for at least 16 to 20 random characters with uppercase, lowercase, numbers and symbols enabled. Length matters more than complexity tricks, because every extra character multiplies the combinations an attacker would have to try.

Some sites only allow certain symbols or ban them entirely. Turn symbols off in the generator, keep the length at 20 characters or more to preserve strength, and generate again. If a site also caps the length, use the maximum it allows and enable every character type it accepts.

Shorten the generated password to the site's stated maximum, but compensate by enabling all character types so the shorter password stays as unpredictable as possible. Avoid trimming a password by hand in predictable ways, such as deleting only the symbols, because patterns make guessing easier.

Save each generated password in a reputable password manager instead of a notes file, spreadsheet or browser sticky note. Use a unique password for every account, so one leaked credential cannot unlock your other accounts, and let the manager fill them in for you.
