Setting secrets on GitHub Profile level?

I want to use Github Actions to push docker images to Docker Hub.
I know that i can set the secrets for this on each repository - however, this is quite cumbersome if you have to repeat this for each repository!?
Is there any way to set the secrets on the GitHub profile level? I have seen in the documentation that you have to change the account to an organization, but this also has other implications, e.g. that I lose all my SSH keys!?
Really no other way?
