It's pretty good. The only complaint I have is the "login" field is the username or email. If you have a username that you must use to log in, there is no "email" field for that login, though I guess you could just put it in that login's note section. That's a very minor complaint. Otherwise it has worked flawlessly on my android and windows pc and Linux mint pc. I moved from dash lane and it's overall smoother and more convenient than dash lane. And the UI is better.

BUT. The most important thing here. The king of features. The big one. Is the ability to instantly generate a new email address that redirects to your main proton address for use in various online accounts. If you pay for Proton that means you have unlimited of these. I am currently in the process of purging my Gmail and having a different, unique email for EVERY online account. Not a single one will have my raw, main Proton email address. These are unrelated to the contents of your main address (unlike how Gmail does the address+extra@gmail thing) so they are completely anonymous. They are also revokable at any time so if you start getting ANY spam emails at all, even a single one, you know where it came from and you can change that affected account to use a new address and simply delete the affected/leaked address.

These addresses are generated and integrated into Proton pass so it's crazy simple to use them. The hard part is going through all your existing accounts and requesting an email change retroactively but new accounts? There's no reason to not use a randomly generated email address. Not even my family knows my root email. Everyone gets a new one. By default, it includes the name of the site in the email address for easy identification. You can choose to customize it too, even change the domain to one of a few available.

I promise I'm not sponsored or something lmao. I just really fucking love the anonymity and control this kind of system gives you, while at the same time being super convenient.

Edit: pair this with an anonymous card service like privacy.com and you're so fucking solid.
