Secure Password Generator
Generate secure passwords, passphrases, policy-compliant credentials and developer secrets — and analyze password strength, entropy and crack-time instantly. Built for developers, security engineers and everyday users. 100% in-browser, nothing transmitted.
Info
A strong password should contain at least 16 characters, mix uppercase and lowercase letters, numbers and symbols, reach at least 80 bits of entropy, avoid dictionary words, keyboard patterns and personal information, and be unique to every account. Store it in a reputable password manager and pair it with multi-factor authentication.

| Method | Security | Convenience | Phishing-resistant | Best use |
|---|---|---|---|---|
| Password | Medium | High | No | Legacy systems |
| OTP (SMS) | Low | High | No | Avoid — SIM swap risk |
| OTP (TOTP app) | High | Medium | No | Baseline MFA |
| Push MFA | High | High | Partial | Enterprise SSO |
| Passkey (WebAuthn) | Very High | High | Yes | Primary auth — recommended |
| Hardware key (FIDO2) | Very High | Medium | Yes | Admins & high-risk |
| Biometric (device) | High | Very High | Yes | Local unlock + passkeys |
MFA Security Advisor
Password Manager Advisor
A password manager generates, stores and autofills unique credentials for every site you use — the single highest-impact security upgrade most people can make.
- Unique passwords per site eliminate credential stuffing risk.
- Built-in phishing protection: autofill won't trigger on lookalike domains.
- Encrypted vaults sync securely across devices.
- Most managers now support passkey storage as well.

Key Takeaways
- Length beats complexity. A 20-character password is exponentially stronger than a complex 8-character one.
- Aim for 80+ bits of entropy for personal accounts and 128+ bits for cryptographic secrets.
- Never reuse passwords. One breach should never compromise a second account.
- Use a password manager + MFA. Prefer passkeys or hardware keys over SMS OTP.
- Rotate only on compromise. Forced periodic rotation degrades password quality (NIST SP 800-63B).
Definition · How It Works · Examples
Entropy
Entropy is the log₂ of the number of possible passwords a generator could produce. A 20-char password from a 94-symbol pool has log₂(94²⁰) ≈ 131 bits. Each added bit doubles the search space.
Hashing
Servers should never store plain passwords. They store a one-way hash (Argon2id, bcrypt, scrypt). Even if the database is leaked, the original password isn't directly recoverable.
Salting
A unique random salt is added before hashing each password. Salts prevent rainbow-table attacks and ensure that identical passwords produce different hashes.
MFA
Multi-factor authentication adds something you have (phone, hardware key) or are (biometric) to something you know (password). It defeats most credential-only attacks.
Passkeys
Passkeys are phishing-resistant credentials based on WebAuthn / FIDO2 public-key cryptography. No shared secret leaves your device — there's nothing for a server to leak.
Credential Stuffing
Attackers replay credentials leaked from one site against thousands of others. Unique passwords + MFA + breach monitoring stop this attack pattern entirely.
Best Practices Checklist
- Use 16+ characters for accounts, 32+ for vault master passwords.
- Use a passphrase for things you must memorize (vault master, disk encryption).
- Enable MFA on every account that supports it — prefer passkeys.
- Store all credentials in a reputable password manager.
- Never share passwords over chat or email — use a secure share feature.
- Audit your vault monthly for reused or weak passwords.
Common Mistakes
- Using personal info (birthdays, pet names, employer).
- Predictable substitutions (P@ssw0rd, Sup3r) — crackers know them.
- Reusing a "good" password across multiple sites.
- Writing passwords on sticky notes or unencrypted documents.
- Relying on SMS OTP as your only second factor.
Future of Authentication
WebAuthn
The browser-native API for FIDO2 credentials. Powers passkeys and security-key flows on every modern browser.
FIDO2
Open authentication standard combining WebAuthn + CTAP. Replaces passwords with public-key cryptography.
Hardware keys
YubiKey, Titan, Nitrokey — physical devices that sign challenges on-device. Resistant to phishing and remote attack.
Synced passkeys
Passkeys synchronized via your platform (iCloud Keychain, Google Password Manager, 1Password) for seamless cross-device login.
