Generate strong, random passwords with custom length and character mix — generated locally in your browser, never sent to a server.
This tool runs entirely in your browser — no data is sent to our servers. If JavaScript is disabled, the fully interactive version will not run; enable JavaScript to compute results.
Strong passwords have three properties: they are long, they avoid dictionary words, and they are unique to each account. Length is the most important — a 20-character random password is dramatically harder to crack than a 10-character one, even if both look complex.
The generator uses the browser built-in cryptographic random number generator (`crypto.getRandomValues`). This is the same source of randomness used for HTTPS keys — orders of magnitude better than Math.random() and acceptable for any non-classified use.
A password manager is the best place to store generated passwords. Reusing a single complex password across multiple sites defeats the purpose of complexity — if any one of those sites is breached, every account using the same password is compromised. Generate a unique password per account and let the manager remember them.
No. They are generated in your browser using the Web Crypto API and are not transmitted, logged or saved.
For most accounts, 14+ characters with mixed case, digits and symbols. For critical accounts (email, banking, password manager itself), 20+ characters and a unique passphrase backup.
The meter checks length and character mix. A 30-character password with only lowercase letters scores lower than a 20-character password with mixed types — because adding character classes increases the entropy faster than length alone.
No. Password reuse is the single biggest cause of account compromise. Use a password manager and a unique password per account.
The Secure Password Generator lives alongside Age Calculator, Date Convert to Major Calendars, Date Count Calculator on the Productivity page. That landing page collects every productivity tool Dailiyo publishes, plus the editorial notes on formula sources, review cadence and how each result should (and should not) be interpreted.
