Passchain is a credential provider that allows you to use your USB/NFC security key or your phone secure element for passkeys/fido2/u2f authentication.

Bluetooth keys aren't supported yet.

This app doesn't need the Play Services.

Once installed, go to your system settings > Passwords, passkeys and accounts, then enable Passchain.

WhatsNew:

- 1.0.0 !

- Target SDK 36, dependencies bump, internal work, other bugfixes etc.

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
