Which UI do you use?

Custom UI

Pre built UI

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.

NodeJS

Important

For other backend frameworks, you can follow our guide on how to spin up a separate server configured with the SuperTokens backend SDK to authenticate requests and issue session tokens.

GoLang

import SuperTokens from "supertokens-node";
import ThirdPartyPasswordless from "supertokens-node/recipe/thirdpartypasswordless";

SuperTokens.init({
    appInfo: {
        apiDomain: "...",
        appName: "...",
        websiteDomain: "..."
    },
    recipeList: [
        ThirdPartyPasswordless.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";
            },
        })
    ]
});

Python

import (
    "github.com/supertokens/supertokens-golang/recipe/thirdpartypasswordless"
    "github.com/supertokens/supertokens-golang/recipe/thirdpartypasswordless/tplmodels"
    "github.com/supertokens/supertokens-golang/supertokens"
)

func main() {
    supertokens.Init(supertokens.TypeInput{
        RecipeList: []supertokens.Recipe{
            thirdpartypasswordless.Init(tplmodels.TypeInput{
                GetCustomUserInputCode: func(tenantId string, userContext supertokens.UserContext) (string, error) {
                    // TODO:
                    return "123abcd", nil
                },
            }),
        },
    })
}

Other Frameworks

from supertokens_python import init, InputAppInfo
from supertokens_python.recipe import thirdpartypasswordless
from typing import Dict, Any

async def get_custom_user_input_code(tenant_id: str, user_context: Dict[str, Any]):
    return "123abcd" # TODO

init(
    app_info=InputAppInfo(api_domain="...", app_name="...", website_domain="..."),
    framework='...', 
    recipe_list=[
        thirdpartypasswordless.init(
            contact_config=..., 
            flow_type="...", 
            get_custom_user_input_code=get_custom_user_input_code
        )
    ]
