Writing is an invaluable skill that needs to be trained like every other muscle. Writing forces you to think more about a topic, how to express this clearly and enable others to consume your thoughts asynchronously and at their speed. Check out my training progress and thoughts below.

Security

Why does storing two-factor authentication codes in your password manager make sense?

Modern login systems require a second factor (2FA) to log in, in addition to the standard username and password combination. A Time-based one-time password (TOTP) as a 6-digit number is often used. Password managers like 1Password, KeePass (or respective forks) and others offer the ability to store (and generate) the 2FA TOTP. For a long time, I was asking myself: Why is it recommended to have a Username, Password, and 2FA in the same storage (like 1Password)? Isn’t this against the basic idea of a second factor (regarding the storage places to gain access to)?

At the end of 2023, my peer Dominik Siebel and I handed over the Meetup ownership to Dario Tilgner to continue to run the meetup with a new perspective, new spirit and a new refreshing approach. This blog post summarizes critical learnings from the past 11 years of local tech meetup activities.
