# Create Access Token

Available in Classic and VPC

Create an access token. To create a token, you must have a token generator set up.

Caution

- The token possesses all the permissions of the key held by the user who requested its creation.
- Token generators do not manage the tokens they generate, so they can't be destroyed individually. Therefore, it is crucial to take extra precautions to prevent token leakage.

## Request

| Method | URI |
| --- | --- |
| POST | /kms/v1/keys/{keyTag}/access-token |
