There could be several reasons, why the recipient is asked to log into DocuSign before accessing the document.
This could be related to the authentication settings and login requirements set on the sender’s account, which you can look at in detail in the following DocuSign Support article:

When “Login Required if Signer Has an Account” is ticked, the recipient will need to log into his DocuSign account in order to access the document. This also applies to free DocuSign accounts which the signer may have created after the signing is completed and does not require them to be a DocuSign customer as well.
This could also be related to login requirements set on the recipient’s side, which requires that they are a DocuSign customer as well and have set up additional security related to their domain for DocuSign. Most common would be the “Require login when opening envelopes” which can be set on a domain level to add an additional layer of security to the DocuSign platform, often in combination with Single Sign-on (SSO) being enabled.
