Configure email and SMS behavior

Customize how the email and SMS are sent in your frontend application.

Changing email / SMS resend time interval

These instructions are only applicable if you are using the pre-built UI.

You can set resendEmailOrSMSGapInSeconds to establish a minimum delay before the frontend allows the user to click the "Resend" button. This limit is only enforced on the client-side. For API rate-limiting please check out the deployment section.

import SuperTokens from "supertokens-auth-react";
import Passwordless from "supertokens-auth-react/recipe/passwordless";
import Session from "supertokens-auth-react/recipe/session";

SuperTokens.init({
appInfo: {
apiDomain: "...",
appName: "...",
websiteDomain: "..."
},
recipeList: [
Passwordless.init({
contactMethod: "EMAIL_OR_PHONE", // This example will work with any contactMethod.
signInUpFeature: {
// The default value is 15 seconds
resendEmailOrSMSGapInSeconds: 60,
}
}),
Session.init({ /* ... */ })
]
});

Setting default country for phone inputs

These instructions are only applicable if you are using the pre-built UI.

How do you identify your users?

By default, there is no default country selected. This means that users have to select / type in their phone number international code when signing in / signing up.

If you would like to set a default country (for all users), then you should use the defaultCountry configuration:

import SuperTokens from "supertokens-auth-react";
import Passwordless from "supertokens-auth-react/recipe/passwordless";
import Session from "supertokens-auth-react/recipe/session";

SuperTokens.init({
appInfo: {
apiDomain: "...",
appName: "...",
websiteDomain: "..."
},
recipeList: [
Passwordless.init({
contactMethod: "PHONE",
signInUpFeature: {
/*
* Must be a two-letter ISO country code (e.g.: "US")
*/
defaultCountry: "HU",
}
}),
Session.init({ /* ... */ })
]
});
