Token rotation
Supported in Bolt for Python as of v1.7.0, token rotation provides an extra layer of security for your access tokens and is defined by the OAuth V2 RFC.
Instead of an access token representing an existing installation of your Slack app indefinitely, with token rotation enabled, access tokens expire. A refresh token acts as a long-lived way to refresh your access tokens.
Bolt for Python supports and will handle token rotation automatically so long as the built-in OAuth functionality is used.
For more information about token rotation, please see the documentation.
