Hi @jm1024, welcome to the GitLab Community forum!
There is no talk of entirely remove the ability for username/password basic HTTP authentication. This is not on the GitLab roadmap.
That said, I suggest enabling 2FA on any important accounts as a security best practice, and enabling 2FA will disable the option for basic username/password HTTP authentication for git operations. Additionally, using SSH keys for authorization instead of username/password provides additional security benefits. These are recommendations but not restrictions, so you can continue using username/password authentication for Git operations on GitLab.com for the foreseeable future.
If you choose to secure your account with username/password one-factor auth, I recommend using a strong, unique password.
