Offline tools

The Off-line menu of an open wallet has a set of tools that protect your private information with the same keys that protect your bitcoin. They work on your computer and need no connection and no login.

Tool	What it does
Encrypted Notes	Keep any number of private notes: personal information, instructions, anything sensitive.
Encrypted Files	Store files encrypted inside your wallet and get them back when you need them.
Encrypted Passwords	A password manager: logins, passwords, authenticator codes, notes and tags.
HSM	Turn the wallet into a signing service for your own programs.
Authenticators	Keep a backup of your two-factor (2FA) authenticators, and get the codes without your phone.
Create QRCodes	Make a QR code from any text.
Split a secret	Cut a secret into several parts and put it back together.

To open a tool, open your wallet, click Off-line in the menu on the left, and choose it.

Where this information is kept

Everything these tools save goes to your wallet folder, on the computer that runs the application, encrypted with a key that comes from your wallet. Nothing is sent anywhere.

Keep a copy of your wallet folder

Your words bring back your bitcoin, and the key that opens these files. They do not bring back the files themselves. If you lose the wallet folder, the notes, files, passwords and authenticators stored in it are gone. Copy the folder to a safe place regularly. It is safe to copy: everything in it is encrypted. The wallets page shows where the folder is.
