# Consul ACL Token Update

Command: `consul acl token update`

The `acl token update` command will update a token. Some parts of the token like whether the
token is local to the datacenter cannot be changed.

## Usage

Usage: `consul acl token update [options]`

#### API Options

@include 'http_api_options_client.mdx'

@include 'http_api_options_server.mdx'

#### Command Options

- `-description=<string>` - A description of the token

- `-id=<string>` - The Accessor ID of the token to read. It may be specified as a
  unique ID prefix but will error if the prefix matches multiple token Accessor IDs

- `-merge-policies` - Merge the new policies with the existing policies.

- `-merge-roles` - Merge the new roles with the existing roles.

- `-merge-service-identities` - Merge the new service identities with the existing service identities.

- `-meta` - Indicates that token metadata such as the content hash and Raft indices should be
  shown for each entry.

- `-policy-id=<value>` - ID of a policy to use for this token. May be specified multiple times.

- `-policy-name=<value>` - Name of a policy to use for this token. May be specified multiple times.

  token. May be specified multiple times. Format is the `SERVICENAME` or
  `SERVICENAME:DATACENTER1,DATACENTER2,...`

  rules. This will cause the legacy token to behave exactly like a new token
  but keep the same secret.

specified grant equivalent or appropriate access for the existing clients using
this token. You can find examples on how to use the parameter in the [legacy
