Me costó un poco conectarla al principio pero siguiendo la pista de la documentación lo logré en seguida. Una maravilla para la seguridad de nuestras contraseñas!

Requires an application installed to work.

Edit: It turns out the checkbox for Browser Integration with Firefox/Tor Browser became unchecked for some reason. After rechecking it, it works without a problem.

I've gotten KeepassXC set up on Brave and Vivaldi already. But this Firefox extension just gives me the error: "Key exchange was not successful" when I try to reload the connection.

Just doesn't work.
Behaviour is so random. Extension works for some sites, and completely fails for others (about 70% of the websites I browse).
The most frustrating thing, is that this green icon appears in the login field, but nothing happens when you press it.
To be noted, this is consistent whichever browser I use (FF or Chrome) and whichever OS I run (Windows 10 or Linux Mint).

I gave a KeepassXC and the browser extension a try because it looked promising, and the KeepassXC GUI is nicer to plain Keepass, but it seems I have no other option than revert to Keepass + RPC pluging + Kee browser extension.

Sad.

EDIT: see bottom for additional (positive) impressions and alternatives.

Original Review:

This is almost perfect, but KeePassXC-Browser is having problems with certain websites which require more than a UserID and Password field.

For example, on the American Airlines site, a username, *last name* and PW are required. While KeePassXC allows me to enter additional attributes like "Last Name: Doe" into advanced, there does not seem to be a way to invoke pasting it into the form.

Even If one uses the "choose custom login fields" there is no way to set the last name field as one of the options . . .

Ah, well. At least there is auto-type! :-)

EDIT: The developer is fantastically responsive, as seen below (and I was also e-mail directly with further comments, a nice touch!). I pointed out the built-in documentation (of KeePassXC) is missing the "KPH:" detail (required in KeePassXC-**Browser**) given in the response (but *is* shown in the online docs which I had not yet read).

Hopefully the built-in docs and online docs become better synchronized.

If you anyone still has problems with KeePassXC-Browser, it seems there are other Firefox add-ons which can connect to KeePassXC such as "KeePassHttp-Connector."

Also, standalone add-ons such as "Owl" (not yet reviewed, but much newer than...) or "KeePass Tusk" make the promise of not needing to install a connector to KeePassXC in the first place.

Would love to see this as a featured plugin. Great work being done here. Thanks for all the effort!

A pain in the Ass !!
It work like one time every 20 time !! Most of the time I have to use the copy/past function of KeepassXC!

On another review you said :
"Did you know that copy/paste with passwords is not very safe. Almost every application has direct access to your clipboard. Our extension is a great way to prevent that kind of stealing. Auto-Type is another good option for you."
But what "great way"? As it never work, your extension is garbage as much as copy/past a password !!!

Waste of time. It's less hassle to cut and paste from Keepass manually
