## Usage
```shell-session
$ boundary credentials update [type] [sub command] [options] [args]
```
### Command options
- `-description` `(string: "")` - A description to set on the credential.
- `-id` `(string: "")` - The ID of the credential to update.
- `-name` `(string: "")` - A name to set on the credential.
- `-version` `(int: 0)` - The version of the credential to update.
If you don't specify a version, the command performs a check-and-set automatically.
#### Usages by type
The available types are `json`, `ssh-private-key`, and `username-password`.
The `credentials update json` command lets you update a JSON credential.
#### Example
The following example updates a JSON credential with the ID `csst_1234567890`:
```shell-session
$ boundary credentials update json \
-id csst_1234567890 \
-name devops \
-description "For DevOps usage"
```
#### Usage
```shell-session
$ boundary credentials update json [options] [args]
```
#### JSON object credential options
The following options are specific to JSON credentials in addition to the command options:
- `-bool-kv` `(map: {})` – A key=value Boolean value to add to the request's object map.
You can specify this option multiple times.
This value can be a reference to a file on disk (`file://`) or an environment variable (`env://`) from which Boundary reads the value.
- `-kv` `(map: {})` – A key=value pair to add to the request's object map.
This option can also be a key value only which will set a JSON null as the value.
If you provide a value, Boundary automatically infers the type.
Use `-string-kv`,`-bool-kv`, or `-num-kv` to override the type.
You can specify this option multiple times.
This value can be a reference to a file on disk (`file://`) or an environment variable (`env://`) from which Boundary reads the value.
- `-num-kv` `(map: {})` – A key=value numeric value to add to the request's object map.
You can specify this option multiple times.
This value can be a reference to a file on disk (`file://`) or an environment variable (`env://`) from which Boundary reads the value.
- `-object` `(string: "")` - A JSON map value to use as the entirety of the request's object map.
Usually this is sourced from a file using `file://` syntax.
This option is exclusive with the other kv flags.
- `-string-kv` `(map: {})` – A key=value string value to add to the request's object map.
You can specify this option multiple times.
This value can be a reference to a file on disk (`file://`) or an environment variable (`env://`) from which Boundary reads the value.
The `credentials update ssh-private-key` lets you update an SSH private key credential.
#### Example
The following example updates an SSH private key with the ID `clvlt_1234567890`:
```shell-session
$ boundary credentials update ssh-private-key \
-id clvlt_1234567890 \
-name devops \
-description "For DevOps usage"
```
#### Usage
```shell-session
$ boundary credentials update ssh-private-key [options] [args]
```
#### SSH private key credential options
The following options are specific to SSH private key credentials in addition to the command options:
- `-private-key` `(string: "")` - The SSH private key associated with the
credential.
This value can be a reference to a file on disk (`file://`) or an environment variable (`env://`) from which Boundary reads the value.
- `-private-key-passphrase` `(string: "")` - The passphrase associated with the
SSH private key.
Boundary ingores this value if the private key does not require a passphrase or if you do not supply a private key.
This value can be a reference to a file on disk (`file://`) or an environment variable (`env://`) from which Boundary reads the value.
If you leave this option empty, and the key requires a passphrase, you can enter it manually.
- `-username` `(string: "")` - The username associated with the credential.
The `credentials update username-password` command lets you update a username password type.
#### Example
The following example updates a username password credential with the ID `clvlt_1234567890`:
```shell-session
$ boundary credentials update username-password \
-id clvlt_1234567890 \
-name devops \
-description "For DevOps usage"
```
#### Usage
```shell-session
$ boundary credentials update username-password [options] [args]
```
#### Username password credential options
The following options are specific to username password credentials in addition to the command options:
- `-password` `(string: "")` - The password associated with the credential.
This value can be a reference to a file on disk (`file://`) or an environment variable (`env://`) from which Boundary reads the value.
- `-username` `(string: "")` - The username associated with the credential.
