denied: requested access to the resource is denied when I try to push my Docker image to my DockerHub repository

I have images of a code that makes summaries of document files (pdf, docx ...). I created a Docker image that I wanted to share online on Dockerhub. But strangely I am getting rejected with an access denied.

remplacement@remplacements-MacBook-Pro SugiPerso % docker images

So, I am silverchair! And I logged in.

(venv) remplacement@remplacements-MacBook-Pro SugiPerso % docker login

Logging in with your password grants your terminal complete access to your account. 
For better security, log in with a limited-privilege personal access token. Learn more at https://docs.docker.com/go/access-tokens/

I tried to verify specifying my username, but I can't log in even if I'm sure of my password (it's the one I use for hub.docker.com):

(venv) remplacement@remplacements-MacBook-Pro SugiPerso % docker login -u silverchair
Password: 
Error response from daemon: Get "https://registry-1.docker.io/v2/": unauthorized: incorrect username or password

I tried creating a personnal access token but still got the error:

(venv) remplacement@remplacements-MacBook-Pro SugiPerso % docker login -u sliverchair
Password:

The error is because you have a typo in your username:

% docker login -u sliverchair
Password: 
Login Succeeded

...

% docker push silverchair/summarize:latest

You need to tag your image with sliverchair/summarize:latest instead of silverchair/summarize:latest to be able to push to your user's repositories.

This shows that you are not logged in with that user:

Login to Docker Hub (with username silverchair), and in your user settings generate a personal access token. Use this token to login. A PAT is required if you have enabled 2FA. If you cannot login to Hub with that username, double check that you entered the correct username and password.
