Migrating from KeepassXC, running into issues and questions

Hey @autostatic, I apologize for our delayed response here. I'll be happy to address the questions/issues you have regarding 1Password for Linux.

Command handler
KeepassXC has the option to open applications and to use templating in the invocation of the command. Does 1Password support such a feature? >KeepassXC uses the cmd:// handler for this but it looks like 1Password only supports https:// and https://?

1Password for Linux supports opening network locations (FTP, SSH, SMB) but not a command handler as you've described.

Autofill
Apparently Autofill only works with browsers and nothing else on Linux? KeepassXC has an Auto-Type feature that allows you to fill in anything anywhere >that also includes templating. Are there any plans to bring the autofill functionality to Linux?

Although 1Password in your browser (extension) can auto-fill fields while browsing the web, this is not something that can be done within desktop applications. We don't have any plans to share at the moment regarding such a feature.

With that said, filling in applications can be made easier by using Quick Access. Quick Access lets you find any item you need without leaving the app you're working in. It remembers the items you use most frequently to give you relevant suggestions. Or, you can search for items across all of your accounts and collections. Check out this guide on how to use Quick Access to fill in apps: Get to know Quick Access.

Auto-lock
Unfortunately this feature does not work on my machine. When I lock my user session 1Password remains unlocked. This has been brought up before but still >doesn't seem fixed. Any plans on looking into this? Glad to help out! Current situation won't make my CISO happy :(

This is a known issue with XFCE/xflock 4 (the script that handles XFCE locking sessions) not locking properly. Essentially 1Password is listening for the right type of call to lock but xflock4 is not notifying 1Password to lock. A possible workaround would be to remap Super+L to also activate the screensaver. This can be done by navigating to your Keyboard Settings > Application Shortcuts > edit the Super+L shortcut to the following: sh -c "xfce4-screensaver-command -a; xflock4"

This should trigger the screensaver as well as the default locking behavior when using the Super+L shortcut. I found that it takes 2-5 seconds after the screensaver appears for 1Password to lock. I understand that this may not be an ideal solution but hopefully it's a viable workaround for the time being.

Drag and drop
This doesn't seem to be supported when editing an item? It would be great if Add more - Attach a file when editing an item would not open a file window but >a field where you could drag and drop your files. With a button beside it to search for files yourself which then opens a file window.

I can certainly see how this could be a useful feature! While I can't make any promises, I'll be happy to pass this suggestions along as a feature request on your behalf to our product team.

Custom secret key length
I seems like the secret key lenghth is fixed? Would be great if you could use your own (larger) secret keys.

The length of your Secret Key is fixed and can't be customized. If you're interested in learning more about Secret Key security, I would suggest checking out page 11 of our security whitepaper: 1Password Security Design

I hope this helps. Let me know if you have any further questions.
