To **load multiple identities** use the `identities` style, For example:
```zsh
zstyle :omz:plugins:ssh-agent identities id_rsa id_rsa2 id_github
```
----
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.

----
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`.
