I am a long time Proton and 1Password user. I really wanted to move to Proton Pass because I like the security architecture better (except for the use of the standard Proton account to log in and not a separate master password and a separate unique key like 1P).
I have been reading this forum for a while and many people say that Proton Pass is almost ready for prime time, so I thought I'd give it a try.
It didn't take long to realize that it is not ready yet and there is a long way to match the 1P features I like the most:
1. PP does not have the use of tags like 1P.
2. No ability to move and reorder vaults, and to set up a default vault for new items.
3. Every time you create a login with an alias, 2 items get created - the alias itself and the login. I can see why there should be 2 different items, since you have to manage the alias. However, they get mixed in the same vault, and you have to move them on a separate vault called "Alias" which is cumbersome.
I wish there was a dedicated section just for the "Alias" management separated from the rest of the items (or at least put all the aliases in a special vault).
Even better, if they want to integrate SimpleLogin aliases inside the Proton Pass app as it seems to be the plan, why not bring the full functionality? Because even if you create the alias in Proton Pass, you have to use SimpleLogin to manage it (for example, disable the alias, create a reverse alias or similar).
4. Extra custom fields - some of the element "type" templates have a the ability to add custom fields but very limited. And some like cards or notes don't allow user to add extra fields which is a bummer. And if you don't use a field, it doesn't get hidden.
Also, for the items that actually allow users to create an extra field, those are limited. You don't even get a field to enter an additional "password" (although you could use the "hidden text" for that purpose, but still you can't create the password in that field).
Some services such as crypto exchanges do have 2 or 3 different passwords (one to login the site, one for trading and one for personal data modification).
5. Can't add my passports, health cards, fidelity programs, bank accounts, ssh, routers, etc. because there are no templates for those. It would be awesome if they could add those, but even better let people create their own templates.
6. Of course given the above limitations, my data as imported from 1P is terrible and some fields don't even get imported properly. Giving the more than 1000 items I have in 1P this makes it very difficult to migrate and manage.
7. Clipboard management - this is an important security feature, whenever a password or 2FA is copied to the clpboard, it should be emptied automatically by the app so the clipboard is not storing sensitive information.
8. I am very much used to the quick access feature of 1P especially when I need to fill passwords on apps that are password protected (including passwords for some crypto wallets. It is a really handy feature and PP doesn't have something like this.
Of course I didn't try it extensively in respect of usage, some people are reporting that when some log ins have two separate pages - one for the email and a different for the password and then the 2FA field gets opened, it doesn't really work properly. This sometimes happens with 1P as well (although very little) in which the quick access feature again comes in very handy to get the data to fill into such websites.
9. Only one dark theme - which is not properly designed, at least is very hard to read for me. Please make it more readable and also add a light theme (or even more themes such as in Proton Mail web app).
At the end, being a 1P power user, I decided that Proton Pass is not ready for me at this time, which is a bummer since I really wanted to make the switch.
Hope that Proton Pass continues to improve and gets eventually as feature rich as I need to make the move.
