Go to Customers > Contacts > choose 'Unverified contacts' from the hamburger menu > check the required contacts click on 'Send activation email'.

This will send a secure link to the customer's email, which they can use to set up a password.

Alternatively, you can go to Admin > Workflows > Email Notifications > Requester notifications > toggle the user activation email ON.
