    // Check password string to be of minimum length of 8 characters and should have
    // atleast 1 digit, 1 upppercase letter and 1 special character
    if (validateTor.isAtleastLength(str, 8)
        && validateTor.hasAtleastOneDigit(str)
        && validateTor.hasAtleastOneUppercaseCharacter(str)
        && validateTor.hasAtleastOneSpecialCharacter(str)) {
    
        // Valid Password
    
    } else {
       // Invalid Password, handle in ui
        edt_password.setError("Password needs to be of minimum length of 8 characters and should have " +
