User Management

How to manage your authenticated user in Flutter

Get current user

Once your user has been authenticated, you can call passage.getCurrentUser() which will return a PassageUser object. When the user is no longer authenticated, this method will return null.

Here's an example:

PassageUser? passageUser = await passage.getCurrentUser();
if (user) {
  print('User ID: ${user.id}');
} else {
  print('No authenticated user');
}

Methods for updating user

Change contact info

To change the user's phone number or email, you can follow the examples below. Note that the user will receive a verification message where they'll need to confirm the change.

// Change email for authenticated user
String newEmail = 'new@email.com';
await passage.changeEmail(newEmail);
 
// Change phone for authenticated user
String newPhone = '155555555555';
await passage.changePhone(newPhone);
 

Manage user passkeys

The following CRUD operations are available for authenticated user passkeys. Note that each of these methods could throw an error that you'd need to handle.

// List user's passkeys
PassageUser? user = await passage.getCurrentUser();
List<Passkey> userPasskeys = user.webauthnDevices;
 
// Create a new passkey
Passkey newPasskey = await passage.addPasskey();
 
// Edit name of passkey
String passkeyId = 'XXXXXXXXXXXXXX';
String passkeyNewName = 'My favorite passkey';
await passage.editPasskeyName(passkeyId, passkeyNewName);
 
// Delete/revoke a passkey
await passage.deletePasskey(passkeyId);
 

Sign out user

To sign out your user and remove their tokens from the user's device (more on this in the next section), you can simply call passage.signOut() .

await passage.signOut();
