No. A Link button cannot sign you in to a website. The Link button puts Pipedrive field values and text into a URL
and opens the URL. It cannot type data into the fields of a web page, for example a sign-in form. See
[Link button](/docs/buttons/link-button).

The best solution is a website that supports single sign-on. The website then signs you in automatically.

If the target page must know that a click came from OneClick, use a Signed link. The Signed link does not sign you
in. It lets the target page verify the click. See [Signed link](/docs/buttons/link-button/sections/signed-link).
