The latest update of Proton Pass added 14 new item types, plus fully customisable item creation from scratch.

The status of this idea should probably be advanced to "STARTED" or "COMPLETED", as appropriate.

The identity section is super helpful, but it feels a bit too rigid right now. Not everyone stores the same kind of info—some might need to save things like “Library ID,” “Health Insurance Number,” or other personal details that don’t fit into the default fields.
It would be awesome if we could add or rename fields ourselves. Customizable fields would make the app way more flexible and useful for different people and use cases.

Bank cards + type of payment system (including international and local ones) + expiry date + CVV/CVC

Regarding Tax ID - it is very dangerous thing, as every country has it's own format for Tax ID, so Tax ID itself without country's name is nothing. Or one will need to implement arbitrary text field for it (as tax id could be number or numbers + letters). The same for passport numbers.

Item types and templates are the biggest issues for me, trying to migrate from Datavault. There surely are some very common ones, like bank account, software activation keys, local user accounts and logins to encrypted volumes...
Notes are a workaround for some of that data, but it would be nicer with dedicated fields in a vault record. Very often there always is a basic "login name" and "password" situation and some extra fields that vary. Maybe the most elegant solution is to let users create their own custom vault record types.

Currently, Proton Pass (PP) allows text notes to be associated with vault entries via entry edit. However, while the feature gives the appearance that notes have two parts: a field name and the actual text note. The hint text in the edit box shows "Field name", but then there is no facility to enter separate text that is associated with such a field name, for the "field name" becomes/is the actual note!

It would be GREAT if one could indeed have a separate field name for vault notes, e.g., "Activation code" associated with the text "ASDFJK-QWERTY-POIUYT-ZXCVBN" (for a software program, e.g.). Also, being able to click-to-copy the associated text (ONLY! Not the field name) is the obvious desireable capability desired.

Also SSH Keys would make sense. 1Password has this and it works great.

And add an SSH Agent / CLI around the Keys

One could create their own vault, but in particular the option to create and share Wifi-QR codes would be a helpful new feature!

This would be HUGE especially with some older video games/programs need a serial key or subscription authorization.

Allow users to store Wi-Fi passwords in the app.

I'd suggest a broader approach : let users add custom fields and. sections to all types of items including notes. Better even, user defined templates.

Yeah honestly I also have non-Credit card payment options which I'd like to store. Here in germany we have Girocards which allow you to pay but they have different field which makes it impossible to store. I could maybe use a dummy login for my card but when I switched over from 1Password I was able to use the normal card type there. No idea why it's so restrictive

Yes, in my country there's a couple of extra fields that are usually asked for when using cards, and it'd be more convenient to have that information in the entry.

Today I needed to store extra information for one of my cards, and I realized cards don't support custom fields.

Obviously manually filling in credit card numbers on a website sucks. Or even copying them in. Not the end of the world, but is a basic feature in probably every other major password manager.

Just noticed these don't exist. Didn't come over on my import from 1Password as a result. Can always look back to 1Password for these, but never sure if something had custom fields or not. Also, as I add new credit cards there's nowhere to put any custom fields since 1Password is only there for me now for what was there when I dropped it for Pass. Can't update it anymore.

Either auto-detect or ability to manually choose the brand with corresponding icon

Would be great if the identity type could be updated as follows:
- automatically create 'full name' field (enter first, middle and last name separately with option to change the 'full name' field if necessary)
- date input for birthdate instead of text field
- address auto-complete / validation + translations (for international shipping)

This would be very nice as having Pass Monitor flag all my pins as weak passwords reduces the usefulness of Pass Monitor
