It is possible to create a self-signup link to client portals. This option is particularly useful if you would like to ask your clients to fill and sign a form that is embedded in a portal but do not have time to invite each client individually.

To generate a link go to your client group and select the option as shown below:

the link can be revoked at any time. If you use a subdomain or own domain for portals, the self sign-up link will respect that.

You can send the link to your clients in an email.
