Plugin or shortcode that show author’s URL

Hi,

I wonder if anyone of you have come across a plugin or shortcode that will allow the author URL to be shown.

For example, if my site is gamecrawl.com, the author’s page will be at https://gamecrawl.com/author/johndoe.

I am looking for a shortcode or plugin that will allow me to show https://gamecrawl.com/author/johndoe in either the author’s page or the post submitted by the author.

I have like to show this particular url(https://gamecrawl.com/author/johndoe)in the widget.

Thanks,
