What support exactly? Years ago I added Yubikey support[0] to KeePassXC. You'd have to migrate your database to KeePassXC and you could use any combination of keyfile, password, and YubiKey.

It's not exactly what you are asking for, but KeepassXC supports OnlyKey [0], and OnlyKeys can enter a password just pressing a button, plus they have HMAC support, so the KeepassXC experience can be:

1. Plug in Onlykey and unlock if necessary.

2. Open database in KeepassXC.

3. Press button in Onlykey with the KeepassXC password.

4. Press any button again when it asks for HMAC challenge.

Sounds like you should switch to KeePassXC if that's what you need.
