And this is what they say about them: Originally, I've arranged Michal's training primarily for my colleagues because "of course I already know these things"... Michal has changed my mind in the first hour of the first day and continued to do so for the whole two days. Thanks to this training I finally understood some of the attack/defense concepts in full depth, and especially in the right context. — Jan Pospíšil, Senior PHP developer, Czech Radio
Come to my public trainings, everybody's welcome:

- HTTPS for developers and admins September 26, 2019 Praha
Trainings in Prague are held regularly in the middle of March, June, September, and December, in other cities irregularly.
Any public training can also be turned into an in-house training. As an extra, I offer these in-house-only courses:
Top 10 coffee brands based on how much their names are used as passwords. Look, not every password research has to be meaningful.
Yesterday, Google announced yet another Security Key to be used for two-factor authentication (2FA, sometimes 2-step verification, 2SV) for Google's services. This one is built directly into Android 7+ so you may already have it in your pocket. It uses Bluetooth (but pairing isn't required) and currently works only in Chrome and Chromium-based browsers – Google says it's a beta version. And that's basically all we know about it. I use 2FA where possible, I recommend using it whenever possible so I just had to try it.
Yesterday I checked Czech websites in “Collection #1” and others (like “Collection #2” to “Collection #5”, “BigDB”), today I've checked Slovak sites. We're neighboring countries and historically have a lot in common, many Czech users have accounts on Slovak sites as well, so it seemed like a good idea.
