# Rotate Passwords

This document will explain how to rotate datasource passwords using the `sdm admin datasources update` command. You can also use this command to update any other aspects of your datasources.

### Get the JSON Template for your Datasource

StrongDM supports dozens of datasources, and each has its own import/update format. To get the current JSON state of the datasource you want to modify, run `sdm admin datasources list -j -e > update.json` command to get a JSON document that you can modify. This command will put information for all datasources into `update.json`.

### Example Update JSON

The `password` field is not included in the JSON export, but you can add it as seen below. Though each datasource type has a bunch of different fields, however, all you'll need is `name` and `password` for the purposes of password update. You can remove any fields you're not using.

{% hint style="info" %}
The `name` field must be unique for each datasource.
{% endhint %}

```json
[
  {
    "type": "postgres",
    "name": "postgres datasource",
    "password": "newPassword",
  },
  {
    "type": "mysql",
    "name": "mysql datasource",
    "password": "newPassword",
  }
]
```

### Run the Update

Once you have your modified JSON ready to go, you can update the password(s) (and any other fields you've modified) by running `sdm admin datasources update --file update.json`.
