Manage Email/Password Users


If you have enabled the email/password provider in your Realm app, you can register a new account, confirm an email address, and reset a user’s password in the client code.

Register a New User Account

To register a new user, pass a user-provided email and password to the RegisterUserAsync() method:

await app.EmailPasswordAuth.RegisterUserAsync(userEmail, "sekrit");

Confirm a New User’s Email Address

To confirm a newly-created user, pass a confirmation token and tokenId to the ConfirmUserAsync() mehtod.

Use Deep Links in Mobile Apps

Mobile applications can handle email confirmation directly in the app by configuring deep linking in Android, universal links in iOS, and/or URI handlers for the Universal Windows Platform (UWP).

await app.EmailPasswordAuth.ConfirmUserAsync("<token>", "<token-id>");

Reset a User’s Password

To reset a user’s password, first send the user a password reset email:

await app.EmailPasswordAuth.SendResetPasswordEmailAsync(userEmail);

Password reset emails contain two values, token and tokenId. To complete the password reset flow, you can reset the user’s password on the client or by calling a custom function on the backend.

Reset the Password on the Client

To reset the password on the client, your UI should prompt the user to enter a new password and the token and tokenId values. You pass these values to the ResetPasswordAsync() method:

await app.EmailPasswordAuth.ResetPasswordAsync(
    myNewPassword, "<token>", "<token-id>");


To access the token and tokenId values sent in the password reset email, you can use a custom password reset email containing an Android deep link or iOS universal link.

Call a Reset Function

If you have defined a backend function to reset the user’s password, you pass the user’s email address and new password to the CallResetPasswordFunctionAsync() method. The function will likely require additional parameters, as shown below:

await app.EmailPasswordAuth.CallResetPasswordFunctionAsync(
    userEmail, myNewPassword,
