Often development tools have built-in git repository managers and developers may feel more comfortable using these integrated git plugins.

In order to use the git plugins on your IDEs, you need a method of authentication with Solvay's gitlab that is not SSO. 

Personal access tokens (authentication over HTTP)

You must use personal access tokens to authenticate against git (Gitlab) over HTTP. They are the only accepted password when you have Two-Factor Authentication (2FA) enabled. 

Setting up Personal Access Tokens

Go to your profile page and cick on Access Tokens.

From here, you can create your own Access tokens which will function as your password when you authenticate your IDE against git (Gitlab).
