Strongly support this.
The current password field auto-detection often fails or triggers password generation instead when I need to fill existing passwords.
Pasting password from right-click would solve these issues.

This one's the number one annoyance when it comes to using Proton Pass as a web extension for me. I feel like I run into an input field that Proton doesn't recognize a lot more often than I used to with competitors, and it's obviously not great, having to manually paste stuff over. It seems fairly straightforward to add this feature with the context menus API, and it would help smooth over a lot of that friction.

The feeling I'm getting so far on this site, is that Proton is very slow to improve their software, for as long as some things have been wants for users and asked-for here. I subscribe to the beta versions of Proton software where they offer that. That said, I do think that Proton's software is overall pretty good. The glaring lack of commonly expected software behavior functionality is "odd" (for lack of, perhaps, a better term that escapes me at the moment). It seems like they are reinventing things like edit CONTROLS from scratch wherever they are used, rather than having anything like self-contained packages of functionality that are reused throughout a program ("controls", in the Windows development realm, e.g.). Aside: it's "odd" (not if you're not a sottware developer) that users would associate basic non-application-specific functionality to a specific application program like ProtonPass and BitWarden.

This is still a big miss.

Agreed on this ask. Right click to paste works on the Mac Firefox extension, but not on the Mac app. This is a baseline usability feature.

Currently, edit boxes in ProtonPass do not allow right-clicking with the mouse and thereby making pasting into the edit box not as easy as it can be (Shift-Insert from the keyboard works, though as an alternative). Please enable this or explain why it will not be enabled. The same issue may be present in all Proton products, so this is actually a request for ALL of the products to allow this functionality, be it the desktop apps, the web apps, or the browser extensions.

Dashlane also has this feature. It's how I usually handled issues with autofill.

silly that this isn't on proton pass. seems basic af

I absolutely agree. This is an essential feature that is also present in other managers like BitWarden, for example and extremely useful.

For example, you want to change the password on an account by first editing it in your ProtonPass (since you want to modify the generated password). There is no way (other than copy & paste) to fill the new password into the appropriate fields on the site's account page.

And like the OP stated, there are times where ProtonPass simply does not detect the site's login fields and as such having the appropriate context menu actions would be very helpful.

I hope this gets implemented rather sooner than later, in spite of the low vote count. :-(

I should add that I use the Brave web browser and it does not have a right click context menu when the browser extension is installed.

Too often I encounter websites that, for some reason, Proton Pass does not auto-populate. I would like a 'context menu' item like Last Pass has that will detect the website and allow me to select the username and password. Just as a note, this very problem occurred when submitting this request and the email and password field did not offer a Proton Pass entry and I was forced to open the browser extension, filter on my Proton account and individually copy and past the username and password. A context menu would solve this problem.

It makes inputing credit cards so much easier also.

This is how Keeper works as well.
