SSH authentication via Fingerprint scanning over network (TLS Sockets)
About this app
This Android app stores your SSH key phrase and sends it to your PC securely via the LAN when an authorized fingerprint is detected by the Android fingerprint scanner.
This app is free open-source software (licensed MIT)
The PC must either run Linux or Windows to use FiSSH.
FiSSH for Linux is available on GitLab together with install instructions at: https://www.gitlab.com/ioanm/fissh-desktop/blob/master/INSTALL.md.
FiSSH for Windows uses the Windows Subsystem for Linux. The Windows edition is also open source and published to: https://www.gitlab.com/ioanm/fissh-windows.
To install FiSSH for Windows run the command inside WSL (Windows Subsystem for Linux) UBUNTU distro: curl https://www.gitlab.com/ioanm/fissh-windows/raw/master/Release/install.sh | sudo bash
The PC app then returns the received passphrase to OpenSSH and the standard ssh binary completes the login process.
It is important to note that none of the FiSSH apps have access to private key file and that FiSSH uses TLS sockets with certificate validation to prevent man-in-the-middle attacks!

Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be dev.ioanm.fissh is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 7.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall FiSSH first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of FiSSH, and a listing is removed when the evidence for it stops holding up.

The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
