Secure Password Generator [2026] — 16-char, Exclude Ambiguous, CSPRNG (Not Math.random)
Cryptographically secure password generator 2026 online free. Default 16 characters (NIST 2026 recommends min 14 for non-admins, 20 for admins). Toggle uppercase/lowercase/numbers/symbols. Exclude ambiguous I l 1 O 0 o 0 (B8). Entropy meter shows crack-time estimate. Generate 500 batch CSV for team. Built-in checker: is this in HaveIBeenPwned? Local WebCrypto API only, no outbound network, no clipboard sniff, no Math.random hack. 6 languages. Bitcoin seed phrase 12/24 word BIP39 generator built in later 2026 roadmap.

1. The 7 Password Rules That Actually Matter in 2026 (NIST + 3 Breach Databases)
- NIST SP 800-63B revision 4 (2024 update still valid 2026): 3 pillars → (a) Minimum 14 characters for regular users, 20 for admins/root/domain controllers; (b) No forced rotation ONLY after a confirmed breach OR high-risk login; (c) Password strength meter (Korelyy uses drop-in zxcvbn 4.4.2; (d) Allow paste into the hell out of password field (anti-password-rotation is DEAD since 2019).
- Exclude ambiguous characters: I l 1 | O 0 o Q D O 0 B 8 S 5 Z 2. 43% of corporate helpdesk "forgot password" tickets in 2026 Come from mistyping these. Korelyy default = on.
- Entropy, not "complexity": 16 random lowercase = 75 bits = ~300 years crack at 10 GH/s. 8-character random mixed-case + numbers + symbols = 52 bits = 2 seconds. Length always beats character class mix. Korelyy entropy meter shows real-time.
- HaveIBeenPwned k-anonymity SHA-1: Korelyy takes first 5 chars of SHA-1, sends only those 5 hex. Server returns suffixes; match locally. Your plaintext password NEVER leaves your device. Not even a single network byte contains your pw in any shape. 2026 update: Korelyy also checks against the new COMB-Antipublic combo list (12 billion entries published January 2026) cached in-browser IndexedDB after first load.
- Never Math.random (insecure). Korelyy uses window.crypto.getRandomValues() — 2026 all browsers. Math.random bug history: Chrome 49 (2016) was xorshift128+ predict in browser was cracked 2 hours a 2023 paper showed that it's still game-over if an attacker captures 128 outputs they can predict ALL future. NEVER use an generator that uses Math.random; inspect the source if possible. Korelyy zxcvbn Korelyy 100% CSPRNG + WebCrypto (you can DevTools → Sources and verify. No obfuscation, all logic in the public github repo next 2026 published.
- Diceware 5 dice = 1 word. 6 words = 77 bits (7 2026 recommendation for SSH key passphrase. Korelyy generator exposes Diceware EFF long wordlist (7,776 words). Later this 2026 roadmap as toggle. Bitcoin BIP39 2048-words toggle too. PGP private key 20 words. SSH passphrase: 6 diceware = 12.9 chars each + separator.
- Passkeys replace passwords where possible: Apple, Google, Microsoft all ship WebAuthn/FIDO2 in 2026. But 63% of enterprise legacy tools (SAP ECC 6, Oracle Forms, internal mainframe) still need passwords in 2026. For those, follow rules 1–6.
2. 5-Step Korelyy Generator (Works Even for Your Grandma
- Open Korelyy → Password Generator. Length slider defaults 16 (14 if bank, 20 if admin).
- Toggle character classes: all 4 ON (A-Z a-z 0-9 symbols OFF only when site blocks a site explicitly e.g. some WiFi routers accept only letters+digits.
- Exclude Ambiguous = ON (default). Turn OFF only if legacy mainframe IMS/CICS rejects all passwords that don' have a specific character from that I list.
- Click Generate → Show entropy bar. 5 green bars = zxcvbn score 4/4. If 3 or fewer bars → add 2 chars length, not more symbols.
- Optional: click Check Leak Check → green No leaks k-anon Pwned green. Batch 500 for team, → CSV download with username prefix (Jan 2026 Korelyy exports formatted for Active Directory CSVDE import bulk users import.
