-By default, access keys expire in 60 days. You can specify a different expiry duration by using the `--ttl` option and passing in a [human readable duration string](https://github.com/jkroso/parse-duration#parsestr) (e.g. "2d" => 2 days, "1h 15 min" => 1 hour and 15 minutes). For security, the key will only be shown once on creation, so remember to save it somewhere if needed!

-
-```shell
-code-push access-key patch <accessKeyName> --name "new name" --ttl 10d

 ### Proxy Support
 
 By default, the `login` command will automatically look for a system-wide proxy, specified via an `HTTPS_PROXY` or `HTTP_PROXY` environment variable, and use that to connect to the CodePush server. If you'd like to disable this behavior, and have the CLI establish a direct connection to CodePush, simply specify the `--noProxy` parameter when logging in:
