You can use Form Base Authentication.

If you want to continue to use Active Directory, you will need to give an AD account to these users. Otherwise, SharePoint also supports Forms Based Authentication and SAML token-based authentication.
Note that these authentication methods are not mutually exclusive. You can use any combination of authentication methods supported by the authentication mode of the Web Application (SAML token-based authentication is only supported when your Web Application is in Claims Based mode).
For more information, see Plan authentication methods .
