Two-factor authentication is easy to get mostly right. And dangerous to get slightly wrong. The basic idea is simple: - Generate a TOTP secret - Show a QR code - User scans it with an authenticator app - User enters a 6-digit code - Server validates the code But the details matter. The first mistake is enabling 2FA too early. If you enable it before the user confirms their first code, you can lock them out of their own account. The correct setup flow is: 1. Generate a pending secret 2. Show the QR code 3. Ask the user to enter the first code 4. Validate the code 5. Only then activate 2FA 6. Generate recovery codes The second mistake is issuing a full access token after password login. If the user has 2FA enabled, the password should only get them a short-lived limited token. That token should only allow one thing: Validate the 2FA code. Only after the TOTP code is valid should you issue the real access token. And then there are the security details people often skip: - Encrypt TOTP secrets at rest - Prevent code reuse within the verification window - Rate limit failed attempts - Hash recovery codes before storing them - Show recovery codes only once 2FA is not just a QR code screen. It’s a full authentication flow. I wrote a detailed walkthrough for implementing 2FA in ASPNET Core with TOTP, QR codes, recovery codes, and the correct login/setup flow: milanjovanovic.tech/blog/how-to-im…

Dapper 𝗵𝗮𝘀 𝗮 𝗯𝗶𝗴 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲 𝗽𝗲𝗻𝗮𝗹𝘁𝘆 𝘄𝗵𝗲𝗻 𝘆𝗼𝘂 insert multiple rows. Here is how to address this problem 👇 Developers love Dapper for blazing-fast reads. But for inserting or updating many rows, it becomes painfully slow (even slower than EF Core). But Why? Dapper sends each row to the database one by one. 10,000 rows = 10,000 round-trips. And here is another problem: ↳ You need to write a lot of boilerplate code when using Dapper. Here is what most developers do when using Dapper: ❌ Write manual INSERT and UPDATE SQL statements ❌ Build complex SQL with hundreds of parameters by hand ❌ Write CREATE TABLE scripts And the problem is that you don't have type safety when writing SQL commands inside strings. When something goes wrong you will only know at runtime. There is a much better way. In my latest video, I show how to solve this with 𝗗𝗮𝗽𝗽𝗲𝗿 𝗣𝗹𝘂𝘀. 👉 𝗦𝘁𝗼𝗽 𝗪𝗿𝗶𝘁𝗶𝗻𝗴 𝗖𝗼𝗺𝗽𝗹𝗲𝘅 𝗦𝗤𝗟 𝘁𝗼 𝗦𝗮𝘃𝗲 𝗗𝗮𝘁𝗮 - 𝗟𝗲𝘁 𝗗𝗮𝗽𝗽𝗲𝗿 𝗣𝗹𝘂𝘀 𝗗𝗼 𝗜𝘁 𝗳𝗼𝗿 𝗬𝗼𝘂. Dapper Plus gives you clean, simple methods for every write operation. 𝗙𝗿𝗲𝗲 𝗦𝗶𝗻𝗴𝗹𝗲 𝗠𝗲𝘁𝗵𝗼𝗱𝘀: → SingleInsert - insert one entity without writing SQL → SingleUpdate - update one entity → SingleDelete - delete one entity → SingleMerge - upsert in one line (insert or update) → SingleSynchronize - keep your data in sync with the source → CreateTable - create the table directly from your C# class No more manual SQL. No more parameter mapping by hand. Just call the method and Dapper Plus handles the rest. All single methods are 𝗳𝗿𝗲𝗲 𝘁𝗼 𝘂𝘀𝗲. 𝗣𝗮𝗶𝗱 𝗕𝘂𝗹𝗸 𝗠𝗲𝘁𝗵𝗼𝗱𝘀 (for high performance): → BulkInsert → BulkUpdate → BulkDelete → BulkMerge → BulkSynchronize This is where the real magic happens. I inserted 10,000 product records into the database: ❌ Dapper: 7,000 ms ✅ Dapper Plus BulkInsert: 300 ms That is over 𝟵𝟲% 𝗳𝗮𝘀𝘁𝗲𝗿 with a single line of code. Dapper Plus supports SQL Server, PostgreSQL, MySQL, Oracle, MariaDB, and SQLite. Watch the full video and see every method in action. P.S.: You can get a free trial for this library and test for 30 days, and you can extend the trial for another month as needed.

The Outbox pattern gets all the attention. But reliable publishing is only half the problem. Your service can publish a message correctly. The broker can deliver it correctly. Your consumer can process it correctly. And you can still process the same message twice. That’s the reality of at-least-once delivery. A timeout, crash, or network blip can happen after your consumer finishes the work but before the ACK reaches the broker. So the broker does the safe thing: It redelivers the message. This is where the Inbox pattern helps. Instead of processing the message directly, the consumer first writes it to an `inbox_messages` table. Duplicates are ignored with `ON CONFLICT DO NOTHING`. Then a background processor picks up unprocessed messages and handles them in batches. This gives you: - Idempotent message reception - Independent retry control - Horizontal scaling with `FOR UPDATE SKIP LOCKED` - Fewer duplicate side effects leaking into your business logic The Outbox makes publishing reliable. The Inbox makes consumption reliable. You usually need both if you want event-driven systems that behave well under failure. I wrote a full breakdown of how to implement the Inbox pattern in .NET with PostgreSQL and RabbitMQ: milanjovanovic.tech/blog/implement…
