Use cases / Personal backups
Replace post-it notes and unencrypted storage
Master passwords, TOTP secrets, sensitive files — encrypted using a passphrase only you know, printed on paper or saved as a file.
The problem
Some secrets are too important for everyday tools
Master passwords
Password manager master password is the single key to your digital life. Losing it means losing access to everything. Post-it notes and shared documents are not the answer.
TOTP secrets
Authenticator apps and hardware keys like YubiKey do not always allow backing up TOTP secrets. Losing access to your authenticator means getting locked out of your accounts.
Recovery codes
Storing two-factor recovery codes on your everyday computer defeats purpose of using authenticator app on another device or YubiKey.
Sensitive files
Sharing sensitive documents by email or cloud storage exposes them to interception. Most cloud providers can access your files as they are not end-to-end encrypted.
The solution
Two ways to protect your secrets
Create encrypted backup
Encrypt any secret using passphrase in an encrypted QR code backup called a block — printed on paper or saved as a file replacing the post-it note.

Encrypt and share files securely — send archive through one channel and passphrase through another, achieving end-to-end encryption.

Create block
Enter your secrets, choose a strong passphrase and create a block. Print block on paper or save as PDF — only you can decrypt secrets.
Store block safely
Store block in home safe, filing cabinet or secure storage. Passphrase can live in your password manager. Storing block and passphrase separately creates two-factor recovery.
To restore, scan block, enter passphrase and view secrets.
Create standalone archive
Drag and drop files
Drag and drop files or folders into Superbacked. Choose a strong passphrase and create a standalone archive — a single encrypted file you can save anywhere.
Share securely (if applicable)
Send archive and passphrase via separate channels — for example, archive by email and passphrase by Signal. Neither channel alone exposes the contents.
To extract, drop archive into Superbacked, enter passphrase and extract files — same experience on macOS and Linux, no account required.
What Superbacked does not protect against
No solution protects against everything — being honest about that is part of earning your trust.
Passphrase reuse
Superbacked enforces strong passphrases but cannot prevent reuse. If passphrase is reused from a breached service, brute-force protection is bypassed. Consider using built-in passphrase generator.
Lost passphrase
If you lose passphrase, block or blockset becomes permanently unrecoverable. Store passphrase in your password manager or another secure location.
Operational security
If someone gains access to both block and passphrase — for example, through unlocked password manager — secret is compromised. Lock devices when away.
Compromised machine
If malware is running on computer when you create a block or blockset, secret could be captured before encryption. For high-stakes secrets, use Superbacked OS.
For high-stakes secrets, use Superbacked OS — a hardened operating system that runs offline and persists nothing to disk.
