Use Octa Pass on this device only, on your computer and phone
The desktop app and the iPhone and Android apps can now keep a vault with no account and no server. You can keep several on one device. Each vault has its own master password and, where the computer has a security chip the app can use, is bound to it, so a copy of its file is useless elsewhere.
Back up to an encrypted .octapass-backup file, or pick a folder and each change is backed up there, keeping the newest seven. Turn on sync moves a vault into a new account as it is, encrypted.
Auto-type and AutoFill now follow the Ask on every fill switch. See local vaults.
