 ## Limitations
 
-### Conflict with Dockerhub personal access tokens and 2FA auth
-
-Pushing READMEs to Dockerhub currently only works with username/password and **not** with [personal access tokens](https://docs.docker.com/docker-hub/access-tokens/). If you have [2FA auth](https://docs.docker.com/docker-hub/2fa/) (two-factor authentication) enabled for your Dockerhub account you're effectively using a personal access token. This is an unfortunate Dockerhub API limitation.
-
-There are indications (in issues and forum posts) that a new API for Dockerhub might be coming up sooner or later that might fill this gap. Fingers crossed. 🤞

 ### Problem with Harbor2 OpenID connect logins
 
 This tool currently doesn't work for Harbor2 users that that authenticate through a 3rd party [OpenID Connect (OIDC) provider](https://goharbor.io/docs/1.10/administration/configure-authentication/oidc-auth/) like auth0, Keycloak, okta, dex, etc).
