Need to add the password for the username in the email template

I need to some help. I have created the welcome email template in which I need to show the username and password.
I have added the field name as below.
Username: ~Contact.Email~
Password: ~Contact._Newpassword~
but the password is not showing in the email.
Can you please help me how to show it in the email.

The password field you have listed is a custom field, not the default Keap password field. That is probably the issue.

So, Can you please let me know how the password will be call on email template. Like password is not showing in the email.

I have added all the fields name but still it is not working.
Is there any attribute which need to add for the password?
