I've been using this extension (and BitWarden in general) for about 18 months now. I was using KeePass, the Lastpass before, and glad I switched. Generates a password or passphrase, you control the length and what's included. Love the way you can detach the dropdown box and put it to the side when switching between tabs. A little off-topic, but BitWarden has a good browser interface, separate Win 10 desktop app, and Android app.
