Build passwords that meet strict policies in seconds. Use hardened presets, remove lookalike characters, force every character set, and copy a fresh secret without anything leaving your browser.
Client-side generation, no uploads
Secure password generator
Generate compliant, high-entropy passwords with one-click presets. Characters never leave your device; randomness comes from the browser crypto API.
Strong
Target 70+ bits for personal accounts, 90+ for admin, 120+ for long-lived keys.
Custom settings
Based on preset: recommendedQuick guidance
- Use 16+ characters for personal accounts; 24+ for admin, SSO, and vaults.
- Enable all sets and "Use every enabled set" for strict policy checks.
- Rotate credentials and store them in a password manager, never in plaintext.
- This tool runs locally; refresh or close the tab to clear the history.
Preset playbook
- Recommended: 16 characters, all sets, removes lookalikes; great default for most accounts.
- Admin / SSO: 24 characters with every set and required mix; suited for vaults, infra, and IdPs.
- No Symbols: 20 characters for legacy apps that reject punctuation or special glyphs.
- Numeric PIN: 8 digits for Wi-Fi or device codes when symbols and letters are banned.
Flip to custom if you need to match exact policy rules, then lock in length and required sets.
Operational guidance
- Use a password manager and never reuse secrets across services.
- Aim for 90+ bits of entropy for admin, long-lived, or shared credentials.
- Copy and rotate: regenerate before pasting into tickets, docs, or chat.
- Close or refresh the tab to wipe the local history in the generator side panel.
Frequently asked questions
Is anything sent to a server when I generate a password?
No. The generator runs completely in your browser and uses the Web Crypto API for randomness. No passwords or settings are sent or logged.
How strong are the presets?
Presets start at 16 characters with every character set and avoid lookalike symbols by default. The hardened preset jumps to 24 characters for long-lived admin credentials.
Can I force every character set to appear?
Yes. Enable "Use every enabled set" and the generator will include at least one lowercase, uppercase, number, and symbol when those sets are selected.
