About SynthPass

SynthPass: The Zero-Vault Password Synthesizer Conventional password managers are part of the problem. They ask you to trust a "vault"—a centralized database of your most sensitive secrets that lives on a server, waiting to be breached. SynthPass is the solution. It doesn’t store your passwords; it synthesizes them. ELIMINATE THE TARGET With SynthPass, there is no database for a hacker to steal. Your passwords exist only for the split second they are generated, calculated mathematically from the domain name and your Master Key. Because no secrets are stored, there is no central vault for an attacker to find—even if your computer is seized or a server is compromised. NEW IN v2.0: ENHANCED SOVEREIGNTY Version 2.0 introduces a superior synthesis engine for even stronger cryptographic results. The v2.0 Standard: Our most robust generation logic to date, now set as the default. Classic Mode Toggle: Total backward compatibility. If you have legacy passwords generated with the original engine, simply check the "Classic mode" box to generate them exactly as before. CORE ARCHITECTURE Master Key Security: Your Master Key is never stored. It resides in volatile memory only as long as you are using it, before a mandatory Security Auto-Wipe purges it after five minutes of inactivity. WiseHash™ Logic: We don't just hash your key; we "stretch" it. Our WiseHash algorithm evaluates the entropy of your Master Key and applies a variable number of SCRYPT iterations. The weaker the key, the harder the math—forcing hackers to waste years of compute time on simple guesses. Infinite Serials: When a site forces a password change, don't change your Master Key. Just increment the optional Serial; SynthPass remembers the serial and your User ID locally so your password remains unique and high-strength. THE VAULT (LOCAL-ONLY STORAGE) For data that cannot be synthesized, SynthPass provides a secure Vault. Encrypted Notes: Save site-specific instructions, security answers, or research notes. Specific Passwords: If you must use a certain non-synthetic password, store it here. Zero Cloud: Everything in the Vault is encrypted with your Master Key and synced only via the browser’s internal files—never our servers or a third-party cloud. MOBILE & EXTERNAL ACCESS Since the logic is purely mathematical, you can generate your passwords on any device using our secure web apps: New v2.0 Algorithm: https://privacybar.net/mobile (Password tab). Classic Algorithm: https://synthpass.com/app. UPGRADE TO PRIVACY BAR Looking for more than just passwords? Privacy Bar is our comprehensive security suite that includes the full SynthPass 2.0 engine alongside post-quantum encryption, steganography, and secure file management. If you use Privacy Bar, you already have the power of SynthPass 2.0 integrated into your digital sovereignty toolkit. Stop storing your secrets. Start synthesizing them.
