You're looking to compare two secure strings, so you'll need to decrypt them first. Here's an implementation of what you're trying to do:

Write-Host "Hey..!! I am here to compare the password you are entering..."
$pwd1 = Read-Host "Passowrd" -AsSecureString
$pwd2 = Read-Host "Re-enter Passowrd" -AsSecureString
$pwd1_text = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pwd1))
$pwd2_text = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pwd2))


if ($pwd1_text -ceq $pwd2_text) {
Write-Host "Passwords matched"
} else {
Write-Host "Passwords differ"
}
