Generate secure passwords directly in the browser — using cryptographically strong randomness (Web Crypto API). Nothing transmitted or stored.
Recommendation 2026: at least 16 characters, mixed from all four classes. For high-value accounts (banking, admin, main email) use 24–32 characters plus a password manager. Generation runs entirely in the browser — the server never sees the password.
The Free SEO check also covers HTTPS setup, mixed-content issues and security-relevant HTTP headers.
Generated password strength is a function of length × character set, both raised to the entropy bits. A 12-character mixed-case password with digits has roughly 71 bits of entropy. A 20-character one with symbols passes 130 bits — high enough to defeat any current offline attack.
crypto.getRandomValues() uses the OS-level cryptographic RNG.Hacked CMS installations and SEO spam injections are the most common reason small business sites lose organic traffic overnight. Google flags compromised sites in Search Console as Security issues and removes them from results within hours. A strong admin password is a 30-second investment that prevents a 30-day recovery.
