Moving a password to another device without syncing your vault

The password is in your password manager, exactly where it should be. The login prompt is on a different device. Perhaps you are preparing an Android device for a maintenance task. It needs one service password. You do not want to sign it into your email account or give it access to the rest of your password vault just to fill in that field. Typing the password manually is an option. Sending it to yourself is another. Neither is particularly appealing when the value is long, the task is temporary, and you are trying to avoid creating unnecessary copies. We build WithinCells at schukai for this kind of handoff. The question behind it is deliberately narrow: how do you get one secret onto the device that needs it, without setting up more access than the task requires? Transfer is a different job from storage I do not see a handoff tool as a replacement for a password manager. Your vault should remain the place where you organise and retrieve credentials. A transfer tool has a smaller job: help you deliver a selected value to a selected destination. Where your existing password manager already handles that well, use it. There is no benefit in adding another application just to repeat a working process. The interesting case is the exception: a temporary device, a one-off setup, or a login where the usual workflow is unavailable. That is also where I would draw the line. Manually moving a credential for one maintenance task is different from distributing secrets across a fleet. For the latter, use managed provisioning and automated secrets management rather than scaling up manual transfers. OWASP recommends reducing human handling of secrets where possible. ¹ The QR code is the package, not a download link WithinCells uses QR-based device pairing. Transfers are encrypted for the chosen recipient and signed by the sender. In QR mode, the code holds the encrypted transfer itself, rather than a URL for retrieving it. The handoff needs neither a shared network nor a cloud ac
