Password generation, handling, and policy answers

Are generated passwords sent to QCS or stored anywhere?

No. The generator uses the Web Crypto API inside your browser. Generated passwords, passphrases, recovery codes, PINs, and tokens are not sent to the QCS server, analytics, logs, local storage, or a database.

How long should a strong password be?

For a randomly generated password stored in a password manager, 20 to 24 characters is a practical default. NIST requires at least 15 characters for single-factor passwords and recommends allowing at least 64 characters so users can use long passphrases.

Should I use a random password or a passphrase?

Use a long random password when a password manager can store and fill it. Use a randomly generated passphrase when a person must type or remember the secret. Every account should still receive a unique value and MFA wherever available.

Can I use these values for routers, firewalls, Wi-Fi, and API integrations?

Yes, after checking the vendor's accepted length and character rules. Store administrative and service secrets in an approved password or secrets manager, avoid chat and email handovers, and rotate temporary credentials after use.

Security baseline

Modern password security prioritizes length, randomness, uniqueness, and MFA.

The presets favour cryptographic randomness and real operating context. They are starting points, not a replacement for vendor limits, a password manager, secrets management, or multifactor authentication.

NIST-aligned length

Single-factor passwords should be at least 15 characters. Systems should permit at least 64 characters, accept spaces, and avoid arbitrary composition rules.

NIST SP 800-63B guidance

Password-manager first

Use a unique generated value for every account. Enable MFA, allow password-manager autofill, and screen user-chosen passwords against common and breached-password blocklists.

OWASP authentication guidance

Controlled secret handling

Put privileged passwords and service tokens in an approved vault. Keep recovery codes offline, avoid email or chat handovers, and rotate credentials when exposure or compromise is suspected.

Improve password and access hygiene

Use generated credentials inside an approved password manager or secrets vault. QCS can help review administrative access, MFA coverage, shared credentials, service-account ownership, and credential handover controls.
