Which UI do you use?

Custom UI

Pre built UI

Manually generating a link

You can use our backend SDK to generate the reset password link as shown below:

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 EmailPassword from "supertokens-node/recipe/emailpassword";

async function createResetPasswordLink(userId: string, email: string) {
    const linkResponse = await EmailPassword.createResetPasswordLink("public", userId, email);

    if (linkResponse.status === "OK") {
        console.log(linkResponse.link);
    } else {
        // user does not exist or is not an email password user
    }
}

Python

import (
    "fmt"

    "github.com/supertokens/supertokens-golang/recipe/emailpassword"
)

func main() {
    userID := "..."

    linkRes, err := emailpassword.CreateResetPasswordLink("public", userID)
    if err != nil {
        // handle error
    }

    if linkRes.OK != nil {
        link := linkRes.OK.Link
        fmt.Println(link)

    } else {
        // user does not exist or is not an email password user
    }
}

Other Frameworks

Asyncio

from supertokens_python.recipe.emailpassword.asyncio import create_reset_password_link

async def create_link(user_id: str, email: str):
    link = await create_reset_password_link("public", user_id, email)

    if isinstance(link, str):
        print(link)
    else:
        print("user does not exist or is not an email password user")

Syncio

from supertokens_python.recipe.emailpassword.syncio import create_reset_password_link

def create_link(user_id: str, email: str):
    link = create_reset_password_link("public", user_id, email)

    if isinstance(link, str):
        print(link)
    else:
        print("user does not exist or is not an email password user")

Multi Tenancy

Notice that the first argument to the function call above is "public". This refers to the default tenant ID that is used in SuperTokens. It means that the generated password reset link can only be consumed by users belonging to the "public" tenant.

If you are using our multi tenancy feature, you can pass in the tenantId that contains this user, which you can fetch by getting the user object for this userId.

Finally, the generated link will use the configured websiteDomain from the appInfo object (in supertokens.init), however, you can change the domain of the generated link to match that of the tenant ID.
