Secure Password Generator
Create strong, random passwords with the length and character types you choose. Generated in your browser, never sent to a server.
Select at least one character type.
How it works
A strong password is, in practice, a long and unpredictable sequence of characters. The longer it is and the wider the range of possible symbols, the harder it becomes for anyone to guess or crack it by trial and error.
This tool builds the password by drawing character by character from the sets you enable: uppercase letters, lowercase letters, numbers and symbols. You set the length with a slider and tick which types go into the mix. With every adjustment, a new password is generated instantly.
The draw uses the browser's own cryptographic random number generator — the kind of randomness used in security contexts — rather than a predictable sequence. Nothing is sent over the internet: the password is born and stays on your device. The strength indicator gives a quick sense of how resistant your chosen combination is.
When to use
Use it whenever you need to create a new password and don't want to fall back on the same one you always use. Reusing a password across sites is one of the biggest security risks: if one service leaks, all the others are exposed.
It's ideal for new sign-ups, for replacing old and weak passwords, or for generating passwords for devices and Wi-Fi networks. Combined with a password manager — where you store each one without having to memorize it — this tool covers the routine of keeping different, genuinely strong passwords for different accounts.
Practical examples
Password for an important account
For email or banking, it's worth going big: a length of 16 to 20 characters with uppercase, lowercase, numbers and symbols enabled. That produces something like a meaningless sequence with more than 90 possibilities per position — practically impossible to guess.
Easy-to-type password
If the password will be typed often on a poor keyboard, you can uncheck symbols and use only letters and numbers, increasing the length to compensate. Less variety, but more length still keeps the password strong.
Common mistakes
The most dangerous mistake is prioritizing "easy to remember" over "hard to guess". Birthdays, names, "123456" and keyboard sequences are the first things an attack tries. A password that's memorable for you is often predictable for whoever is trying to break in.
Another mistake is thinking that swapping letters for lookalike symbols solves the problem — like "a" for "@" or "o" for "0". These tricks are well known and barely improve the security of a word that already exists in the dictionary. What really matters is randomness and length.
Finally, many people create a strong password and reuse it in several places. Individual strength doesn't protect against leaks: if the password appears in a breach of one site, it has to be changed everywhere. The ideal is one unique password per service, stored in a password manager.
Frequently asked questions
Is the generated password sent to a server?
No. All generation happens in your browser, using your device's own random generator. The password never travels over the internet and is not stored by us.
What password length is considered secure?
For most services, 12 to 16 characters with a variety of types is already quite secure. For critical accounts, such as email and banking, 16 or more is a good choice.
Do I need symbols in my password?
Symbols increase variety and therefore strength. But if a system doesn't accept them, you can compensate by increasing the length with letters and numbers.
How will I remember a random password?
The recommendation is not to try. Use a password manager to store each one securely — that way you only have to remember one master password.
