# Rotate profile authentication token
### Importance of periodic token rotation and impact
As explained in the documentation for [deploying agents](/getting-started/deploy-enforcement-point.md), security best practices dictate that authentication tokens should be rotated periodically.
The existing token will be invalidated but existing agents that were already registered are not affected.
{% hint style="warning" %}
Once rotated, in order to allow deployments of additional agents, **you must** replace all deployment scripts/configuration files/key vault entries that contain the now-invalid token.
{% endhint %}
### How to invalidate existing token and create a new one
When browsing to **Policy->Profiles** and editing any profile, its authentication token, used for authentication new deployments, can be found under Authentication section:
Clicking on the icon will invalidate the current token and create a new one that can be copied.
Clicking on the  icon will invalidate the current token and create a new one that can be copied.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://waf-doc.inext.checkpoint.com/how-to/rotate-profile-authentication-token.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
