Running bash script after WGET ignores read user input

Question

I'm trying to create a bash script that can be easily downloaded and run from terminal. Inside the bash script there are a couple of user inputs.

Running:

sudo wget -O - https://script.com/script.sh | bash

This will download the script and run it with bash but will ignore the user input in script.sh:

echo "Please enter a username:"
read -p 'Username: ' uservar
echo "Please enter a strong password:"
read -sp 'Password: ' passvar
echo
echo "
user=$uservar
password=$passvar
" >> ~/.data/cred.conf
echo "Succesfully installed."

Running:

sudo wget -O - https://script.com/script.sh && bash ./script.sh

Works fine and prompts for user input. Is there any way to make user input work with a pipe ( | bash ) ?

from comment

| bash <(cat) </dev/tty

why and how it works

• <(cat) construct allows
  • to create a process which reads from inherited input, at this point, it's the pipe output
  • to redirect output to a file descriptor used as a file and process expansion is changed to a string used as a file name
• </dev/tty redirects pseudo terminal device /dev/tty to input of bash process
