Hello Team ABP,
we are happy to use ABP and consuming framework with multiple projects and we are also using Openiddict module for token generation for mobile apis. when we are going process thorough 2FA login and calling 2fa provider api and send email works fine even for verification 2fa code works fine but after verification of 2fa we require to generate openiddict token we are unable to generate token using tokenmanager class this creates the tokenid but payload not returns the token and i also trying to create jwt token with the existing onpeniddict certificates jwt token works but limited scope as compared to normal token created from connect/token our manual token will not works on [authorize] services calling from one appservice to another appservice below is the mentioned code with 2 approaches openiddict and jwt process.
public virtual async Task\<VerifyAuthenticatorCodeDto> VerifyTwoFactorCodeAsync(VerifyAuthenticatorCodeInput input)

var user = await \_userManager.FindByIdAsync(input.UserId.ToString());

<br> we dont have issue on web application as it manages the cookies it self but still we are facing issue to change default pages styling on forgot pages etc pleases share you feedback as soon as possible to resolve those queries these are challenges we are facing.

To generate an OpenIddict access token for a mobile user after successful 2FA verification (so that the token is equivalent to what is returned from /connect/token), you should not manually create tokens using TokenManager or by directly generating JWTs. Instead, you should leverage the OpenIddict authorization flow, ideally by implementing a custom grant type that handles the 2FA verification and then issues a token using the same pipeline as /connect/token.
Recommended Approach
Implement a Custom Grant Type in OpenIddict:
- Create a custom grant type (e.g., "2fa") that accepts the necessary parameters (user ID, 2FA code, provider, etc.).
- In the handler for this grant type, perform the 2FA verification using your existing logic.
- If verification succeeds, create the user principal and call the OpenIddict APIs to issue the token, just like the password or refresh_token grant types.
Why Not Use TokenManager Directly?
- TokenManager.CreateAsync does not generate a JWT access token payload directly; it creates a token entity in the database.
- The JWT returned by /connect/token is generated by OpenIddict's token endpoint, which handles claims, scopes, lifetimes, and signing.
- Manually creating JWTs bypasses OpenIddict's internal logic, which can lead to missing claims, scopes, or incompatibility with [Authorize] attributes.
How to Implement:
- Register your custom grant type in OpenIddict configuration.
- Implement a handler that validates the 2FA code and, if valid, issues a token using OpenIddict's APIs.
- Call /connect/token with your custom grant type from the mobile app after 2FA verification.
Example: Registering a Custom Grant Type
services.AddOpenIddict() .AddServer(options => { // ... other options ... options.AllowCustomFlow("2fa"); options.SetTokenEndpointUris("/connect/token"); options.AddEventHandler<OpenIddictServerEvents.HandleTokenRequestContext>(builder => { builder.UseInlineHandler(async context => { if (context.Request.GrantType != "2fa") return; // Extract parameters (userId, code, provider, etc.) // Perform 2FA verification // If valid, create principal and sign in: var principal = ...; // create principal with claims, scopes, etc. context.Validate(principal); }); }); });
Example: Mobile App Token Request
POST /connect/token Content-Type: application/x-www-form-urlencoded grant_type=2fa&user_id=...&code=...&provider=...
This way, the token returned is fully compatible with ABP's authorization system and works with [Authorize] attributes and internal service calls.
Additional Notes
- For customizing the styling of default pages (like forgot password), you can override the relevant Razor pages or Blazor components in your project. ABP allows you to replace or customize UI pages as needed.
Sources
This approach ensures your tokens are generated in a standard, secure, and ABP-compatible way after 2FA verification.

hi
You can try to add a custom grant type to generate an access token https://abp.io/community/articles/how-to-add-a-custom-grant-type-in-openiddict.-6v0df94z
