Currently, I am using Pinentry Mac from Xcode on my system to sign git commits. For this, I am having to input my passphrase each time I am waiting to sign a commit.
Seeing that my MacBook Pro has a fingerprint sensor I was wondering if there is a pinentry implementation can substitute password entry with a fingerprint check?
THere is no fingerprint support that I can see.
There is however, from this thread, passphrase caching (meaning you enter only once, and never again after that)
See "GPGTools Support / Password management".
Make sure your ~/.gnupg/gpg-agent.conf does not include the line ignore-cache-for-signing.
There is an implementation of pinentry that supports this use-case: https://github.com/jorgelbg/pinentry-touchid
