* Runs on Linux/Mac/Windows and there are compatible clients for Android. Make your own cloud with a RaspberryPi referred by a DDNS and you'll have super powers.
* Auto-type. Is tricky to get it working but once you get it you'll become addicted.
* The UI makes it much easier to copy and paste fields and the notes are clearly visible. I often use the notes to store things like github tokens (for git), etc. However, I keep 2FA TOTP codes on my Pebble watch only. If you keep 2FA codes on the same file as your password then it isn't 2 Factor anymore, right?
Little things that bothered me:
* It took me a while to understand how does the Touch ID/fingertip reader works (you need to turn on the checkbox, press Ok on the authentication modal and then touch the reader). Touch ID is one of those things that suddenly you discover you can't live without.
* The browser add-ins are not always smooth and friction-less. Sometimes you need to reload the page, reopen the db. Chrome's add-in is the hardest to get working. Firefox's is better.
* Edit: forget this. As varjolintu explains bellow, this is wrong. ~~You can't have multiple addresses per entry. Some sites will login with different URL's and KeepassXC will not recognize all.~~
But I am still a fan. I'd give it a 8/10.
