@sajids Thanks for your recent post. Your request is under review and we will get back with further updates. Can you confirm which Pnp SDK are you migrating from? Is it Web SDK , Flutter SDK, etc. ? ---

We are migrating from PNP SDK Flutter to Core Kit SFA Flutter ---

@sajids Thanks for your reply. After checking internally with our Dev team, it is not possible to migrate from PNP Flutter SDK to CoreKit SFA Flutter at the moment. ---

Yes, there is no estimate when the migration feature from PnP Flutter to Corekit SFA Flutter will be available but it is in the pipeline in future. ---

Yes i understand so that is why we created a new project with new custom verifier but i still the same issue ---

@sajids You are setting up SFA Flutter SDK from scratch? This SDK only works for users who have **not enabled MFA**. For MFA enabled users, you’ll see `Error("User has already enabled mfa, please use the Web3Auth PnP Web or Mobile SDKs for login with mfa");`
