Every password manager you've used, including Proton Pass, Bitwarden, and 1Password, stores your encrypted vault on a company's server. Strong encryption on each individual entry doesn't change one structural fact: one server breach can expose every user's vault at once.
Z-TEXT's password manager runs on a fundamentally different architecture. Every entry is encrypted twice — once with a key derived from the wallet seed, once with the master password — then written directly to the BitcoinZ blockchain using zk-SNARKs zero-knowledge proofs. There's no central database anywhere holding passwords in one place, because the blockchain itself is the storage.
How is this different from Proton Pass or Bitwarden?
Both are excellent tools, but both still concentrate every user's vault on one server. Z-TEXT shields vault data directly on-chain — even someone examining the exact block sees only that a transaction happened, never its content.
What happens if you lose your phone?
Restore the wallet from the seed phrase on any device, and the encrypted vault comes back automatically — it's already on the blockchain, waiting. Enter the master password, and everything decrypts. No cloud account, no sync service, no export file to remember.
The honest trade-off
No browser extension means no auto-fill in Chrome or Safari. In exchange, there's no bridge between the browser and the vault — the exact connection point malicious extensions and autofill-phishing attacks exploit in other password managers. Using the vault also requires running a BTCZ wallet.
One tool among four
The vault is part of Z-TEXT's 4-in-1 app — messenger, wallet, password manager, and broadcast channels, all under a single seed phrase. Pricing starts at $3/month, comparable to standalone managers like Proton Pass, but covers all four tools together.
