A class, representing the credentials used for authenticating a User.

Inheritance

Object

Credentials

Namespace: Realms.Sync

Assembly: Realm.dll

Syntax

public class Credentials

Properties

IdentityProvider

Gets the identity provider for the credentials.

Declaration

public string IdentityProvider { get; }

Property Value

Type	Description
String	The identity provider, such as Google, Facebook, etc.

Token

Gets the access token.

Declaration

public string Token { get; }

Property Value

Type	Description
String	The access token.

UserInfo

Gets additional user information associated with the credentials.

Declaration

public IReadOnlyDictionary<string, object> UserInfo { get; }

Property Value

Type	Description
IReadOnlyDictionary<String, Object>	A dictionary, containing the additional information.

Methods

Anonymous()

Creates Credentials for an anonymous user. These can only be used once - using them a second time will result in a different user being logged in. If you need to get a user that has already logged in with the Anonymous credentials, use Current or AllLoggedIn.

Declaration

public static Credentials Anonymous()

Returns

Type	Description
Credentials	An instance of Credentials that can be used in LoginAsync(Credentials, Uri)

AzureAD(String)

Creates Credentials based on an Active Directory login.

Declaration

public static Credentials AzureAD(string adToken)

Parameters

Type	Name	Description
String	adToken	An access token, obtained by logging into Azure Active Directory.

Returns

Type	Description
Credentials	An instance of Credentials that can be used in LoginAsync(Credentials, Uri)

Custom(String, String, IDictionary<String, Object>)

Creates an instance of Credentials with a custom provider and user identifier.

Declaration

public static Credentials Custom(string identityProvider, string userIdentifier, IDictionary<string, object> userInfo)

Parameters

Type	Name	Description
String	identityProvider	Provider used to verify the credentials.
String	userIdentifier	String identifying the user. Usually a username of id.
IDictionary<String, Object>	userInfo	Data describing the user further or null if the user does not have any extra data. The data will be serialized to JSON, so all values must be mappable to a valid JSON data type.

Returns

Type	Description
Credentials	An instance of Credentials that can be used in LoginAsync(Credentials, Uri)

CustomRefreshToken(String)

Creates a Credentials based on a custom Refresh token.

Declaration

public static Credentials CustomRefreshToken(string token)

Parameters

Type	Name	Description
String	token	A Json Web Token, obtained by a 3rd party source that will be used instead of the ROS-issued refresh tokens.

Returns

Type	Description
Credentials	An instance of Credentials that can be used in LoginAsync(Credentials, Uri)

Remarks

Unlike other Credentials methods, users logged in via the CustomRefreshToken API will not go through the regular login flow (since we already have a refresh token). Instead, the provided token will be used at any point when we need to exchange the refresh token for an access token, e.g. when opening a Realm file. If the refresh token is invalid or expired, the user instance will still be valid and they'll be able to create/open Realms, but those will never be synchronized with ROS. If the token is then updated with a new valid one, existing changes will be synchronized with the server as usual.

To update a refresh token, just set RefreshToken to the new updated value.

ROS must be configured with refreshTokenValidators for this user to ever be able to sync with it.

Facebook(String)

Creates Credentials based on a Facebook login.

Declaration

public static Credentials Facebook(string facebookToken)

Parameters

Type	Name	Description
String	facebookToken	A Facebook authentication token, obtained by logging into Facebook.

Returns

Type	Description
Credentials	An instance of Credentials that can be used in LoginAsync(Credentials, Uri)

Google(String)

Creates Credentials based on a Google login.

Declaration

public static Credentials Google(string googleToken)

Parameters

Type	Name	Description
String	googleToken	A Google authentication token, obtained by logging into Google.

Returns

Type	Description
Credentials	An instance of Credentials that can be used in LoginAsync(Credentials, Uri)

JWT(String, String)

Creates Credentials based on a JWT access token.

Declaration

public static Credentials JWT(string token, string providerName = "jwt")

Parameters

Type	Name	Description
String	token	A Json Web Token, obtained by logging into your auth service.
String	providerName	The name of the jwt provider in ROS. By default, it will be jwt, unless explicitly overridden by the ROS configuration.

Returns

Type	Description
Credentials	An instance of Credentials that can be used in LoginAsync(Credentials, Uri)

Nickname(String)

Creates Credentials based on a login with a nickname. If multiple users try to login with the same nickname, they'll get the same underlying sync user.

Declaration

[Obsolete("The Nickname auth provider is insecure and will be removed in a future version. Please use UsernamePassword or Anonymous instead.")]
public static Credentials Nickname(string value)

Parameters

Type	Name	Description
String	value	The nickname of the user.

Returns

Type	Description
Credentials	An instance of Credentials that can be used in LoginAsync(Credentials, Uri)

UsernamePassword(String, String, Nullable<Boolean>)

Creates Credentials based on a login with a username and a password.

Declaration

public static Credentials UsernamePassword(string username, string password, bool? createUser = default(bool? ))

Parameters

Type	Name	Description
String	username	The username of the user.
String	password	The user's password.
Nullable<Boolean>	createUser	true if the user should be created, false otherwise. It is not possible to create a user twice when logging in, so this flag should only be set to true the first time a user logs in.

Returns

Type	Description
Credentials	An instance of Credentials that can be used in LoginAsync(Credentials, Uri)
