The best password is long, random and used on only one site. Making one up yourself is surprisingly hard — people fall back on names, dates and patterns. This generator picks every character at random.
Passwords are created with your browser’s cryptographically secure random generator. They are never sent anywhere or saved.
How to use
- Set the length — 16 or more is a good default.
- Choose which kinds of characters to include.
- Copy a password and save it in your password manager.
Why use Deftivo
Truly random
Uses crypto.getRandomValues with unbiased sampling, not the predictable Math.random.
Meets site rules
Every chosen character type appears at least once, so “must contain a number and a symbol” rules pass.
Easy to read
Turn on “Avoid look-alikes” to drop 0/O and 1/l/I when you need to type the password by hand.
Frequently asked questions
How long should a password be?
At least 12 characters, and 16 or more for important accounts. Length adds more strength than symbols do.
Is it safe to generate passwords online?
Here, yes: the password is created in your browser and never leaves your device. You can even use the tool offline once the page has loaded.
What does the strength in bits mean?
It estimates how many guesses an attacker would need. Every extra bit doubles the work; 80 bits or more is very strong.
