Upcoming changes to OAuth access tokens

Change effective on 07 March 2024

Starting April 1, 2024, we’ll prefix all newly granted Heroku OAuth access tokens with HRKU-.

Current token example: "57dce771-afad-4c41-a8a5-d10b7fbc743c"
Prefixed token example: "HRKU-57dce771-afad-4c41-a8a5-d10b7fbc743c"

Token behavior remains the same. All current tokens will continue to work and remain unchanged until they’re regenerated. This change allows us to enable additional security features in the future.
