Pinentry dialogue

I couldn't find a way to bypass the pinentry dialogue without a tty. The problem with the pinentry dialogue is that my keybase passphrase is in a password manager so i have to copy it to the dialogue box and this dialogue box does not allow pasting.

The issue names no files, tests, or entry points. Start by reproducing the pinentry dialogue when no TTY is available and check how passphrase input behaves; done means providing a usable non-dialogue path or otherwise resolving the reported input limitation.
