Key concepts

Master password

The password you choose when creating your account. It encrypts your local vault. SecureCrypt cannot reset it for you - that is intentional, and it is why your recovery key exists.

Recovery key

A 24-word phrase generated once, at account creation. It is the only way to restore access if you forget your master password. Write it down and store it somewhere safe and offline.

Vault

An encrypted local database on your device that stores your file records, encryption keys, and settings. It is automatically synced to the cloud so you can restore it on a new device.

.scv files

The encrypted file format used by SecureCrypt. A .scv file contains your original file wrapped in AES-256 encryption. It cannot be opened without the correct password.

Zero-knowledge

SecureCrypt's servers store only encrypted data. No one at SecureCrypt can read your files or learn your password.
