How to fix the issue «Authentication required (repo.magento.com)» while executing Composer commands? (duplicate)

[Bibhuti_Jha]

I want to uninstall this extension on my development server for some days.
Can you please confirm me the uninstall command.

I also followed the provided steps:

How to uninstall a Mage2.PRO extension?

Step 1 composer remove <package name> E.g.: composer remove mage2.pro/stripe Step 2 bin/magento setup:upgrade Step 3 rm -rf pub/static/* && bin/magento setup:static-content:deploy Step 4 rm -rf var/di var/generation && bin/magento setup:di:compile

But when I followed the first steps then it’s not recognised/working.
