Changing OTP format

By default, the generated OTP is 6 digits long and is numbers only. You can change this to be any length you like and have any charset by providing the getCustomUserInputCode function.

import SuperTokens from "supertokens-node";
import Passwordless from "supertokens-node/recipe/passwordless";

SuperTokens.init({
    appInfo: {
        apiDomain: "...",
        appName: "...",
        websiteDomain: "..."
    },
    recipeList: [
        Passwordless.init({
            contactMethod: "EMAIL", // This example will work with any contactMethod
            // This example works with the "USER_INPUT_CODE_AND_MAGIC_LINK" and "USER_INPUT_CODE" flows.
            flowType: "USER_INPUT_CODE_AND_MAGIC_LINK", 

            getCustomUserInputCode: async (userCtx) => {
                // TODO:
                return "123abcd";
            },
        })
    ]
});
