How to read from text file with colon in bash

I have usernames and passwords stored in .txt file with double dot and i would like to read from it and store the first half in variable and second half in variable.

Example : kmyghz1:aa12345bb12345cckmyghz1

cat ./examples/secrets.txt | while  IFS=':' | read variable1 variable2 do \
        echo $variable1 \
        echo $variable2 \
done

Can anyone help?

Thank you for your input and this is the right answer that worked for me!

while IFS=: read -r userName password
do
 echo "$userName"
 echo "$password"
done < ./instabut/examples/secret.txt

IFS=: by itself is not a command; it's a pre-command assignment for the read command. Drop the pipe symbol (|) separating them. You are also missing either a semicolon or a newline character preceding the do keyword.

while IFS=: read variable1 variable2; do
    echo "$variable1"
    echo "$variable2"
done < ./examples/secrets.txt

The backslashes are unnecessary, and parameter expansions should always be quoted.
