The user module creates a link "My account" to /user in the account menu.

This module lets you override the label with text, or the current user's name.

Configuration

/admin/config/people/custom_account_link

Why is this needed?

The default link can be disabled and a new one created with the label you want. But since menu links are content entities, it won't export to config.

This module makes things a little more convenient for sitebuilders.
