Frequently asked questions
Common questions about this tool.
CSPRNGs produce values an attacker cannot predict without breaking the OS or hardware. Password generators should use crypto APIs, not Math.random().
The tool uses your browser’s cryptographic randomness APIs when available, which are suitable for unpredictable passwords.
If the tool exposes character set options, you can disable ambiguous glyphs to reduce transcription errors when reading passwords aloud.
Long memorable passphrases can be excellent if they are unique per site. Random strings from a generator plus a password manager are also a strong pattern.
Attackers try common words and leaked passwords before brute force. Randomly generated passwords avoid human-predictable patterns targeted by dictionaries.
Forced frequent rotation often causes weaker patterns (suffixes). Modern guidance emphasizes length, uniqueness, MFA, and rotation only after compromise.
Misguided UX tries to stop phishing; it hurts password manager users. Pasting from a generator into a manager-backed field is a recommended workflow.
Some managers encrypt vaults client-side so the provider never sees plaintext. That is product architecture; this page’s generator still benefits from local randomness.
WebAuthn and FIDO2 keys prove possession of a device. Strong passwords plus phishing-resistant MFA is the gold standard for high-risk accounts.
Meters estimate entropy or pattern checks (length, variety, breach lists). Generators enforce rules directly; meters help humans judge self-chosen passwords.
