You use API tokens to authenticate yourself when you make authorized API connections. You also need an API token when you associate a VMware Cloud Director instance with a VMware Cloud on AWS SDDC.
An API token has a time-to-live (TTL) period, which you define when you generate the API token. After this time, if you want to continue using the APIs that rely on a token, you must regenerate the token.
After generating an API token, save the token credentials to a safe place.
You can regenerate a token at any time. If you regenerate a token, you revoke all instances of the previous token. If you have used the API token, for example, in one of your scripts, you must replace it with the newly generated API token.
