For example: + +```zsh +zstyle :omz:plugins:ssh-agent helper ksshaskpass +``` + +### `identities` + +To **load multiple identities** use the `identities` style (**this has no effect +if the `lazy` setting is enabled**). For example: + +```zsh +zstyle :omz:plugins:ssh-agent identities id_rsa id_rsa2 id_github +``` + +**NOTE:** the identities may be an absolute path if they are somewhere other than +`~/.ssh`. For example: + +```zsh +zstyle :omz:plugins:ssh-agent identities ~/.config/ssh/id_rsa ~/.config/ssh/id_rsa2 ~/.config/ssh/id_github +# which can be simplified to +zstyle :omz:plugins:ssh-agent identities ~/.config/ssh/{id_rsa,id_rsa2,id_github} +``` + +### `lazy` + +To **NOT load any identities on start** use the `lazy` setting. This is particularly +useful when combined with the `AddKeysToAgent` setting (available since OpenSSH 7.2), +since it allows to enter the password only on first use. _NOTE: you can know your +OpenSSH version with `ssh -V`._ + +```zsh +zstyle :omz:plugins:ssh-agent lazy yes +``` + +You can enable `AddKeysToAgent` by passing `-o AddKeysToAgent=yes` to the `ssh` command, +or by adding `AddKeysToAgent yes` to your `~/.ssh/config` file [1]. +See the [OpenSSH 7.2 Release Notes](http://www.openssh.com/txt/release-7.2). + +### `lifetime` + +To **set the maximum lifetime of the identities**, use the `lifetime` style. +The lifetime may be specified in seconds or as described in sshd_config(5) +(see _TIME FORMATS_). If left unspecified, the default lifetime is forever. + +```zsh +zstyle :omz:plugins:ssh-agent lifetime 4h +``` + +### `quiet` + +To silence the plugin, use the following setting: + +```zsh +zstyle :omz:plugins:ssh-agent quiet yes +``` + +### `ssh-add-args` + +To **pass arguments to the `ssh-add` command** that adds the identities on startup, +use the `ssh-add-args` setting. You can pass multiple arguments separated by spaces: + +```zsh +zstyle :omz:plugins:ssh-agent ssh-add-args -K -c -a /run/user/1000/ssh-auth +``` + +These will then be passed the the `ssh-add` call as if written directly. The example +above will turn into: + +```zsh +ssh-add -K -c -a /run/user/1000/ssh-auth <identities> +``` + +For valid `ssh-add` arguments run `ssh-add --help` or `man ssh-add`. + +## Credits + +Based on code from Joseph M.
