Frequently asked questions
Is it safe to generate a password on a website?
Here, yes: generation uses your browser's built-in secure random source (crypto.getRandomValues) and runs entirely on your device. The password is never sent, logged, or stored — you can verify by loading the page and disconnecting from the internet before generating.
How long should my password be?
16 characters with mixed character sets is a strong default for accounts. For anything protecting high-value data (a password manager's master password, disk encryption), use 20+ characters or a long passphrase.
What does 'exclude ambiguous characters' do?
It removes characters that look alike — such as l, I, 1, O, and 0 — which helps when a password must be read aloud or typed from paper. It slightly reduces the character pool, so add a couple of characters of length to compensate.
Should I reuse a really strong password?
No. Reuse is the biggest practical risk: one leaked site exposes every account sharing the password. Generate a unique password per account and keep them in a password manager.
About this tool
The password generator creates cryptographically random passwords entirely on your device using the Web Crypto API — no generated password ever touches a network. Control the length (up to 128 characters) and which character sets to include: uppercase, lowercase, numbers, and symbols, with an option to exclude ambiguous characters like l, 1, O, and 0 that are easy to misread. A strength estimate updates live, and one click copies the result. For real security, use a unique generated password per account and store them in a password manager.
Like everything on UtilityBase, the password generator runs entirely in your browser — nothing you enter is uploaded or stored on a server. It's free to use with no account required. Browse more generators here.
