Custom

You can use any command line tool that outputs secrets either as a string or in JSON format. Choose the binary by setting secret.command in your configuration file. You can then invoke this command with the secret and secretJSON template functions which return the raw output and JSON-decoded output respectively. All of the above secret managers can be supported in this way:

Secret Manager	secret.command	Template skeleton
1Password	op	{{ secretJSON "get" "item" "$ID" }}
Bitwarden	bw	{{ secretJSON "get" "$ID" }}
Doppler	doppler	{{ secretJSON "secrets" "download" "--json" "--no-file" }}
HashiCorp Vault	vault	{{ secretJSON "kv" "get" "-format=json" "$ID" }}
LastPass	lpass	{{ secretJSON "show" "--json" "$ID" }}
KeePassXC	keepassxc-cli	Not possible (interactive command only)
Keeper	keeper	{{ secretJSON "get" "--format=json" "$ID" }}

passhole	ph	{{ secret "$ID" "password" }}
