remote: Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.

Instead, you need to add PAT (Personal Access Token). 

First, you need to generate a PAT on GitHub following the steps below:

• Settings => Developer Settings => Personal access tokens => Generate a personal access token => Fill the form => click Generate token => copy the generated token, which is something like "ghp_***"

Second, clone or set remote url with PAT

• git clone https://<username>:<githubtoken>@github.com/<username>/<repositoryname>.git
• git remote set-url origin https://<username>:<githubtoken>@github.com/<username>/<repositoryname>.git
