Home / Password Security
Six tools for the security toolkit: password generation, strength testing, passphrases, crypto keys, salts and TOTP 2FA QR codes — all computed locally.
Cryptographically secure random passwords with entropy meter and character set control.
Generate → STRENGTHTest password security with entropy calculation and estimated crack time.
Check → PASSPHRASEMemorable multi-word passphrases from a 1000+ word dictionary.
Generate → KEYSCryptographically secure keys in hex, Base64 or Base32 format.
Generate → SALTRandom crypto salts for password hashing — 8 to 64 bytes, hex or Base64.
Generate → TOTP / 2FAGenerate 6-digit TOTP codes and scannable QR codes for authenticator apps.
Generate →Every tool on this page runs entirely in your browser. Passwords, keys, salts and TOTP secrets are generated using crypto.getRandomValues and computed with standard algorithms — they never touch a server. This is not just a privacy feature; it means the generated secrets are as secure as your device itself.
For password storage best practices, use Bcrypt from the Bcrypt Generator in the Developer Tools category. For general text manipulation, see the Text Tools category.
