# ssh-agent plugin
|
||||
|
||||
This plugin starts automatically `ssh-agent` to set up and load whichever
|
||||
credentials you want for ssh connections.
|
||||
|
||||
To enable it, add `ssh-agent` to your plugins:
|
||||
|
||||
```zsh
|
||||
plugins=(... ssh-agent)
|
||||
```
|
||||
|
||||
## Instructions
|
||||
|
||||
To enable **agent forwarding support** add the following to your zshrc file:
|
||||
|
||||
```zsh
|
||||
zstyle :omz:plugins:ssh-agent agent-forwarding on
|
||||
```
|
||||
|
||||
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.
|
||||
|
||||
```zsh
|
||||
zstyle :omz:plugins:ssh-agent lifetime 4h
|
||||
```
|
||||
|
||||
