Ok. Did some googling came up with the following. Could someone confirm that I’m doing this correctly?
Objective: To save passphrase in cache to an unattended machine so that it doesn’t time out the credentials. Specifically, using https://github.com/docker/docker-credential-helpers, with setup https://github.com/docker/docker-credential-helpers/issues/102#issuecomment-388634452. Steps: use gpg-preset-passphrase Current Setup * ~/.gnupg/gpg-agent.conf * pinentry-program /usr/bin/pinentry-curses * max-cache-ttl 60480000 * default-cache-ttl 60480000 * allow-preset-passphrase * gpg --version * gpg (GnuPG) 2.0.22 * libgcrypt 1.5.3 * Copyright (C) 2013 Free Software Foundation, Inc. * License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> * This is free software: you are free to change and redistribute it. * There is NO WARRANTY, to the extent permitted by law. * * Home: ~/.gnupg * Supported algorithms: * Pubkey: RSA, ?, ?, ELG, DSA * Cipher: IDEA, 3DES, CAST5, BLOWFISH, AES, AES192, AES256, TWOFISH, * CAMELLIA128, CAMELLIA192, CAMELLIA256 * Hash: MD5, SHA1, RIPEMD160, SHA256, SHA384, SHA512, SHA224 * Compression: Uncompressed, ZIP, ZLIB, BZIP2 * gpg2 --fingerprint --fingerprint n...@domain.com * pub 2048R/12312312 2019-03-23 * Key fingerprint = 4567 4567 4567 4567 4567 4567 4567 4567 4567 4567 * uid Name <n...@domain.com> * sub 2048R/11121314 2019-03-23 * Key fingerprint = 8910 8910 8910 8910 8910 8910 8910 8910 8910 8910 Updated Setup using gpg-preset-passphrase only * ~/.gnupg/gpg-agent.conf * We should be able to remove the first 3 line items since we are only using gpg-preset-passphrase * Final file contents * allow-preset-passphrase * Reload gpa-agent.conf file * gpg-connect-agent reloadagent /bye * Setup gpg-preset-passphrase * gpg-preset-passphrase --preset 8910891089108910891089108910891089108910 * Now when you login to that key and enter the passphrase It should cache it until you issue the following command to remove it. * gpg-preset-passphrase —forget 8910891089108910891089108910891089108910 Question: 1. Is the updated setup correct in my assumption for the setup? Thank you in advance for taking the time to help, it is greatly appreciated.

I’m attempting to use gpg-preset-passphrase. But uncertain how to go about enabling it for usage. Could someone direct me or provide me some instructions in how to go about enabling gpg-preset-passphrase?
