Same problem here. My solution: Get a mouse with internal memory for macros, such as Natec Genesis GX78 (old, no longer available, but this is an example). Program your new password on one of the unused mouse buttons or in a different profile. Use the mouse to type the password.
Might be a good product to app-ify. Maybe a USB dongle that acts like a keyboard and controlled by your phone. Give it some sort of 1Password / Bitwarden integration.
I should do this for ssh password entry. Running ssh-agent is still 90% of the story, but it comes up often enough that I'm on a terminal in a remote machine or inside a screen session or something that it would still be awfully useful to be able to just autotype it.
Does it require installing 3rd party software on the host machine? This might not work great for this kind of "shadow IT" application in all environments, whereas one that acts as a USB keyboard might be more versatile.

No, it identifies as a keyboard. It also defaults to generating a password that will use the same scancodes on (most?) western keyboard layouts so that computers configured to default to e.g. QWERTZ or AZERTY will still result in the same password.
Separately from the password aspect, consider how convenient it may be to use your smartphone as a kind of re-reified "clipboard": Use the camera and on-device OCR to copy text, then "paste" it as a virtual keyboard connected over USB.
It's very niche, but in those rare situations it'll be a big time-saver compared to human transcription or the rigamarole of setting up some other kind of data channel.
It can, and I tried this, but in practice we have to change our passwords at my current employer so frequently that I got more irked changing it on the Yubikey (not the least hassle-free of processes, as I couldn't install the Yubikey software on the work machine) than just typing the thing.
