The issue has been fixed. You need to uninstall and install 2FA Login service again. Please let me know if the fix helped you.

Hello @bhargav,

I have answered you here:

User 2fa loggin support

Hello @bhargav, To enable 2FA for a specific user, avoid manually toggling the totpAuthEnabled column, as this alone isn’t sufficient. This column serves as a visual indicator of the 2FA status for a user, not as a control switch. Instead, use the enable2FA method from the TOTP API Service with the logged-in user to activate 2FA. Similarly, to disable it, use the disable2FA method rather than directly toggling totpAuthEnabled. Hope this helps! If you have any further questions, feel free to re…

hello
Thank you it working in rest API call after changing the column name

but
I’m encountering an error during the login process in my .NET Core API. When I attempt to log in as a user with two-factor authentication (2FA) enabled, an error is thrown. Please review the attached screenshot for details.

i tried to down load new DLL and configured in my application but still getting same error

Can you try to logout before login if method IsValidUserToken() return false or Login method returns this error.

Regards, Nikita.

1. I tried to login with new user but still getting same error.

2. what need to pass in usertoken (https://api.backendless.com/api/users/isvalidusertoken/userToken)

NOTE

According to the provided documentation, the API methods for user registration and login are outlined as follows:

• Backendless.Users.register
• Backendless.Users.login

However, after configuring the .NET SDK and referencing the Backendless DLL in my project, I found that the access to these methods is structured differently. Instead of accessing Backendless.Users, I must use Backendless.UserService to perform actions as follows:

• Backendless.UserService.Login
• Backendless.UserService.Register

I wanted to confirm whether this difference is intentional or if there may be an issue with my configuration. Any guidance you can provide regarding this difference would be greatly appreciated.

[bhargav]

hello can you please provide support for upper query!

https://backendless.com/docs/dotnet/users_login.html

public BackendlessUser Backendless.UserService.login( String identity, 
                                                      String password );

public BackendlessUser Backendless.UserService.Login( String identity, 
                                                      String password, 
                                                      bool stayLoggedIn )

https://backendless.com/docs/dotnet/users_user_registration.html

public BackendlessUser Backendless.UserService.Register( BackendlessUser user );

Here the methods for registration and for login.
Maybe you are looking to a wrong sdk?
And another question, have you tried to call logout before login?
Backendless.UserService.Logout();

Regards, Nikita.

[bhargav]

Hello I tried with logout but still getting same error please see attached screen shot…

can you provide me the latest SDK/DLL so that i can configure it.

[Nikita_Fedorishchev]

Which version are you using now?

The latest version at nuget: NuGet Gallery | Backendless.NET 6.7.1 - 6.7.1.
You can add with this line, or with interface in your IDE.
dotnet add package Backendless.NET --version 6.7.1

Best Regards, Nikita.
