Docker: Error: Unauthorized: incorrect username or password on mac OS

Getting the following error when I run anything... 

docker: Error response from daemon: Get https://registry-1.docker.io/v2/library/mysql/manifests/latest: unauthorized: incorrect username or password

Here is how I solved it: 

• Login into www.docker.com with my username and password
• Note down the docker ID which is different than your loginID/email 
• In Terminal now enter the command "docker login" it will ask you to enter your user and password
• If the login is successfull you should get the following message: 

Password: 

Login Succeeded

Now you can run the commands and they should run fine.
