About the Password Generator
Generate cryptographically secure passwords in three modes: random characters (customisable length and character sets), passphrases (random dictionary words joined by a separator) or numeric PINs. Entropy is displayed for each result.
How to use the Password Generator
- Choose mode: password, passphrase or PIN.
- Set length or word count.
- Select character sets (uppercase, lowercase, digits, symbols).
- Generate one or multiple passwords.
- Copy the result.
Frequently asked questions
How long should a password be?
At least 12–16 characters for random passwords. For passphrases, 4–6 words provides equivalent strength and is easier to remember.
Are passphrases more secure?
A 4-word passphrase from a large dictionary has similar entropy to a 12-character random password. Passphrases are easier to type and remember.
Is this truly random?
Yes. Generation uses PHP's random_int() backed by the OS CSPRNG. Results are not stored or logged.
