A strong, unique password is the cheapest defence any online account gets — and the moment you need one is rarely convenient: a new MyGovID login, a Revenue myAccount as the 31 October pay-and-file deadline approaches, a new mobile fresh out of the box, or a long-overdue move to a password manager. This free password generator for Ireland creates a random password from a cryptographically secure source in one click. Set Length to the size you need, pick which character classes to include — uppercase and lowercase letters, digits, basic symbols (%$#@!?&), and complex symbols (.,;[]()^-_=+{}:<>|) — and press Generate.
Security is the whole point, so the generator is built on the Web Crypto API (crypto.getRandomValues), which draws its values from the same cryptographically secure system randomness that TLS and other security-critical operations rely on. Unlike generators based on Math.random() or similar predictable pseudo-random functions, it is built so that seeing one result tells an attacker nothing about the next. Generation happens entirely on your device: the password is never sent to a server, never logged, and never seen by us — there is nothing to intercept and nothing for us to store.
The options make it easy to match most sites' password policies. Every password is guaranteed to contain at least one character from each class you selected — so "must include an uppercase letter and a number" is satisfied automatically — and "Ensure approximately equal number of each character type" is on by default, so no single class crowds out the rest. Turn symbols on for maximum strength, or off for legacy systems that reject them. The "No look-alikes" switch removes the characters people misread most often (Il1O0o), and "Exclude cross-alphabet lookalikes" goes further, also removing letters that look identical across the Latin and Cyrillic alphabets.
Need more than one password, or an unusual policy? Set Count to generate a whole list at once — up to 100 passwords, for example when creating accounts for a team — and once Count is above 1, Output format decides how they are separated: Line break, Space-separated or Comma-separated. Everything else lives under Advanced Options. Turn off "Exclude duplicate characters in one password" to allow the same character to appear more than once. If your language has its own alphabet or extra letters, the generator covers 35 of them — from Ukrainian, Greek and Serbian to Polish, Turkish and Vietnamese — so switch on "Local uppercase letters" and "Local lowercase letters" to mix those characters into the result. And for complete control, "Character pools (one per line)" lets you define your own sets: each line becomes a separate character class the generator draws from.

How is the randomness generated? Your operating system continuously collects entropy — unpredictable noise from hardware events — and feeds it into a cryptographically secure random number generator. When you press Generate, the page's JavaScript requests random values from the browser through crypto.getRandomValues, maps them onto the character classes you selected, checks that every class is represented, and assembles the password. There is no seed to guess, no algorithmic shortcut that specialised password-cracking hardware could replay, and the password never travels over the network — the entire pipeline runs on your device.
Below the result you will see an entropy estimate in bits — a rough guide to password strength: 60+ bits is reasonable for everyday accounts, 80+ is strong, and 100+ is beyond the practical reach of brute force with today's hardware. Two habits matter more than anything else. First, length beats complexity: use 16+ characters for anything important — each extra character multiplies an attacker's work far faster than another symbol class does. Second, uniqueness: when a website suffers a data breach, the leaked login credentials are immediately tried on other services — an attack called credential stuffing — so a single reused password can turn one leak into a full account takeover. Generate a separate password for every account, keep them in a password manager, and enable multi-factor authentication wherever it is offered. Those habits match the everyday advice Ireland's National Cyber Security Centre publishes for people and small businesses. And don't be surprised if a random password contains a short readable fragment or, once duplicates are allowed, a repeated character — random output produces such runs all the time, and they don't make the password any weaker.
