Github announced their intent to require the use of token-based authentication for all authenticated Git operations. They will no longer accept account passwords when authenticating Git operations on GitHub.com:
Generate token:
- Go to your Github token settings
- Generate a token
On Mac:
- Go to keychain Access
- Press login tab and all items
- Click Github key
- Change the password to the recent generated token
On Windows:
Go to Control Panel => User Accounts => Credential Manager
Edit the Generic Credential of github
Paste the token instead of the password
