You will receive an email from MyClient Portal containing a link with which you can create an account.
If you click on the link you can log in with the email address to which the email was sent. The same email contains a password that you can log in with.
Immediately after logging in, you will be asked to enter your own password. You will also receive an SMS verification code that you need to log in. It is therefore important that the correct telephone number is known.
