UmbracoCms.Plugins.2fa

Two-factor authentication plugin for Umbraco CMS. Implements TOTP (Time-based OTP) with EF Core-backed backup code storage.

Targets

  • Umbraco 13 (net8.0)
  • Umbraco 17 (net10.0)

Features

  • TOTP secret generation (Base64-encoded HMAC-SHA1 key)
  • TOTP verification with ±1 time-step window (30-second windows)
  • Backup code generation (8 × 8-char hyphenated codes)
  • Single-use backup code redemption
  • EF Core schema: twofactor.TwoFactorSetups, twofactor.BackupCodes
  • Backoffice dashboard (AngularJS for U13, Lit 3 Web Component for U17)

Database Migrations

Run EF Core migrations to create the schema:

dotnet ef migrations add InitialCreate --context TwoFactorDbContext
dotnet ef database update --context TwoFactorDbContext

API Endpoints

Method Route Description
POST /umbraco/api/twofactor/SetupTotp?memberId=N Generate / reset TOTP secret
POST /umbraco/api/twofactor/VerifyTotp?memberId=N&code=XXXXXX Verify code and enable 2FA
POST /umbraco/api/twofactor/GenerateBackupCodes?memberId=N&count=8 Generate backup codes
POST /umbraco/api/twofactor/UseBackupCode?memberId=N&code=XXXX-XXXX Redeem a backup code
GET /umbraco/api/twofactor/IsEnabled?memberId=N Check if 2FA is enabled

Note on TOTP

The built-in TOTP implementation is a simplified HMAC-SHA1 approach for demonstration. For production, replace with a dedicated library such as OtpNet.
