  To configure the email confirmation and password reset token providers in ABP Framework to use a 6-digit code and enforce the expiration time, you need to ensure that:

  1. You are using the correct token provider (EmailTokenProvider<TUser>) for email confirmation and password reset.
  2. The TokenLifespan is set as desired (e.g., 2 minutes).
  3. The token validation logic checks the expiration as expected.

  Key Points

  • The EmailTokenProvider<TUser> generates a 6-digit numeric code by default.
  • The TokenLifespan property controls the expiration, but the token provider must be correctly configured and used.
  • If tokens are always validating except for the most recent, it may be due to caching, clock skew, or not using the correct provider when generating/validating tokens.

  Correct Configuration Example

  // In your module's ConfigureServices method:
  context.Services.Configure<DataProtectionTokenProviderOptions>(options =>
  {
      options.TokenLifespan = TimeSpan.FromMinutes(2);
  });
  
  context.Services.Configure<IdentityOptions>(options =>
  {
      options.Tokens.EmailConfirmationTokenProvider = TokenOptions.DefaultEmailProvider;
      options.Tokens.PasswordResetTokenProvider = TokenOptions.DefaultEmailProvider;
      options.Tokens.ChangeEmailTokenProvider = TokenOptions.DefaultEmailProvider;
      options.Tokens.ChangePhoneNumberTokenProvider = TokenOptions.DefaultEmailProvider;
  });
  

  Important: Use the Correct Token Provider

  When generating and validating tokens, always specify the provider:

  // Generating a token
  var token = await _userManager.GenerateUserTokenAsync(user, TokenOptions.DefaultEmailProvider, "ResetPassword");
  
  // Validating a token
  var isValid = await _userManager.VerifyUserTokenAsync(user, TokenOptions.DefaultEmailProvider, "ResetPassword", token);
  

  Troubleshooting

  • If tokens are not expiring as expected, ensure that the TokenLifespan is not being overridden elsewhere.
  • Make sure the system clocks are synchronized across your servers (especially in distributed/microservice setups).
  • If you are using distributed cache for identity, ensure cache invalidation is working as expected.

  References

  • OpenIddict Token Lifetime Configuration
  • ABP Support: Customize email confirmation token after successfully confirm email
  • ABP Emailing Documentation

  This approach aligns with official ABP documentation and common ASP.NET Core Identity practices. If you follow the above configuration and always specify the provider when generating and validating tokens, the expiration should be enforced as expected.

  We checked the codes, there is not any code block that sets TokenLifespan except options.TokenLifespan = TimeSpan.FromMinutes(2);

  I'm checking it in my local computer.

  How can I check "distributed cache for identity, ensure cache invalidation is working as expected"?

  hi

  But when we call verify password reset token with 6 digit code it validates all the time except when a new one created.

  What is your code?

  Thanks.

  hi

  The EmailTokenProvider implementation is TotpSecurityStampBasedTokenProvider by default.

  It uses a fixed TimeSpan.FromMinutes(3) value.

  see https://github.com/dotnet/aspnetcore/issues/27088

  Thanks.
