Generate a secure password
A good password is mainly one thing: random, and long enough. The generator in Loclavis creates it directly in your browser, using the cryptographic random source every modern browser provides.
Nothing is transmitted or stored
The generated password appears in the input field and nowhere else. It does not go to a server, does not land in local storage, in your history or in a log file. Copying, saving or printing only happens when you explicitly ask for it.
Why randomness beats special characters
A password like Summer2024! satisfies plenty of rules and is still weak, because it follows a well known pattern. Twenty random characters are effectively unguessable, whatever they look like. So the generator produces real randomness instead of patterns, and does it without bias: a naive calculation would quietly favour certain characters.
Word passphrases
If you have to type or dictate a password, a passphrase is friendlier. Six random words from a list of 512 give exactly 54 bits of randomness and can be read out over the phone without anyone asking about capitalisation. Passphrases are among the extra options in Loclavis Plus.
Reading the strength meter honestly
The meter under the field estimates length and character variety. It cannot tell whether your password appears in a breach database or comes from a well known quote. That is why Loclavis quotes no crack times in years: such numbers look precise and are not.
Keeping the password
A password manager is the best place. If you do not use one, Loclavis offers after protecting to copy the password, save it as a text file or print it. Keep it separate from the protected file: both in the same email attachment defeats the whole point.
