First time? Enter a new master password (8+ characters). It encrypts everything. Lose it, lose access. There is no recovery.
Import wallet key
Paste your 64-character hex private key. You'll then enter your master password to recover your vault from the DAG. One key = one password. If you lost your password, your vault is gone.
Recover from DAG
Enter your vault key (64-char hex from your previous browser) and your master password. We'll fetch your encrypted backup from the DAG and decrypt it.
How your data is protected
🔐 AES-256-GCM encryption. Same standard used by governments. Every entry is encrypted before touching any storage.
🔑 2-factor encryption. Both your password AND wallet key are required. PBKDF2 with 1,000,000 iterations kills brute force.
🎲 Random salt + random IV per vault. Two users with the same password produce completely different ciphertext.
💻 Everything runs in your browser. No servers. No cloud. Your password never leaves your device.
⛓ Kaspa DAG backup. Optional. Encrypted vault stored as a transaction payload - unreadable without both keys.
⏱ Auto-lock after 5 minutes of inactivity. Password wiped from memory.
