Get User Info
There are several ways to fetch information about a user:
- Using their user ID, you can get their email ID, time joined, and metadata that is saved in the user metadata recipe.
- Lastly, you can get the user's session information and access token payload from their session handle (offline mode), or from the currently logged in session object (online mode).
#
Fetching information using the user's email- NodeJS
- GoLang
- Python
You can get a user's information on the backend using the getUserByEmail
, getUserByPhoneNumber
and getUserById
functions:
import Passwordless from "supertokens-node/recipe/passwordless";
async function handler() { const userInfo = await Passwordless.getUserByEmail({email: "test@example.com"});}
You can get a user's information on the backend using the GetUserByEmail
, GetUserByPhoneNumber
and GetUserById
functions:
import ( "fmt"
"github.com/supertokens/supertokens-golang/recipe/passwordless")
func main() {
userInfo, err := passwordless.GetUserByEmail("test@example.com") if err != nil { // TODO: Handle error return } fmt.Println(userInfo) //...}
- Asyncio

from supertokens_python.recipe.passwordless.syncio import get_user_by_email
user_info = get_user_by_email("test@example.com")
#
Fetching information using the user's phone number- NodeJS
- GoLang
- Python
import Passwordless from "supertokens-node/recipe/passwordless";
async function handler() { const userInfo = await Passwordless.getUserByPhoneNumber({phoneNumber: "+1234567891"});}
import ( "fmt"

func main() {
userInfo, err := passwordless.GetUserByPhoneNumber("+1234567890") if err != nil { // TODO: Handle error return } fmt.Println(userInfo) //...}

Using the user metadata recipeCheckout the user metadata recipe docs which shows you how to save and fetch any JSON object against the user's ID. You can use this to save information like the user's name (first_name
and last_name
) or any other field associated with the user.
#
Getting information from the user's sessionThe user's session contains their user ID and the session's payload. You can access this on the backend and frontend as well as whilst the user is online or offline.
More information about this can be found in the session docs.
