How ByteLock protects you
Your master password never leaves your device. Here is what happens under the hood.
You set a master password
A cryptographic key is derived from your password on your device. The password itself is never sent to our servers.
Data is encrypted locally
Every password, card, note, and file is encrypted with AES-256 on your device before being stored.
Only you can decrypt
Without your master password, the encrypted data is unreadable. We store only ciphertext we cannot access.
