I have it and it's terrible IMO.

As another opinion, I use 1Password 4 for Windows, and am quite happy with it.

Then you clearly don't have to use multiple vaults... I've tried using 4 and 6 together - but that resulted only in tears. Enpass looks ok-ish, although a lot more limited with some questionable UI decisions and features (last used in my browser extension? really?)

Enpass doesn't seem to support multiple vaults at all though...

I'm happy with it with Google Chrome, which is what I use on my Windows gaming desktop.

However, on my Surface Pro 4 I use Edge, because it supposedly uses less power than Chrome.

If I've understood the 1Password forums correctly, the Edge integration that they are working on will only be in the subscription version. Those of us staying on 4 will be stuck with manually looking up passwords in 1Password.

Fair enough, I don't actually use any of the browser integrations.

Did they add OTP support to version 4 of the windows client? Last I saw it was not supported, so it was not super useful to me.

Not that I know of? I'm not really familiar with OTP, nor do I use it.
