Typical Workflow
The password generator is ideal for quickly creating strong credentials when registering new services. Typical workflow: 1. Select password length (recommend 12+ characters) 2. Check required character types (uppercase/numbers/symbols) 3. Copy the generated password directly. All processing happens locally in your browser with no network transmission risks.
Developers often use it to batch-generate test account passwords. The 'Exclude ambiguous characters' option (e.g., 0/O, 1/l) prevents manual entry errors. Note: Generated passwords only appear on the current page and disappear after refresh - save them to a password manager promptly.

FAQ
Are passwords uploaded?
No. Everything uses local crypto.getRandomValues.
Why are some special symbols missing from generated passwords?
Some websites restrict symbol types (e.g., only @#%). The tool uses widely compatible symbols by default. Check 'Include all symbols' for expanded options, but note symbols like $ may be treated as escape characters in certain systems.
