Pair the devices
Pair both devices once with QR codes and compare the security codes on both screens.
WithinCells
The password is on one device. You need it on another.
Transfer passwords, API keys, and other short confidential text to one selected device—without sending it to yourself through email, chat, or a cloud clipboard.
Android Community 0.1.7 is public. Desktop 0.1.5 is a preview.
A clear path from device to device
Transfer and input are two separate steps
Transfer the text
Select the target. Use a QR code or encrypted Bluetooth between paired WithinCells devices.
Enter it once
Enter the received text at the target. On Android, the one-time WithinCells keyboard is the preferred path.
Typical situations
Built for the gap between two devices
- Move an API key from a development computer to a test device.
- Enter one password on a server without network access.
- Use a recovery code on a second device without placing the whole password vault there.
Complements your password manager
WithinCells does not store a password collection. It handles the deliberate last step to another device.
It is not a general file-transfer tool and cannot make a compromised target trustworthy.
No shared network required
Each transfer belongs to one selected target
No account or cloud
A QR code contains the complete encrypted transfer. No relay service is required.
Selected recipient
Only the paired target has the private key needed to open it. The sender signs the transfer.
One use in WithinCells
After output, the receiving device locks the transfer. The original password itself remains valid.

Scan QR codes directly
Do not place pairing or transfer QR codes in screenshots, photos, or chats. Clipboard output is marked as a fallback. Bluetooth keyboard output is a separate path and is not the same end-to-end transfer.
