1Password v7.8.8 & Paste.app v3.0.11 on macOS 11.5.2 works fine for me, anything copied from 1P is passed along to Paste.app. I've unchecked "Ignore Passwords & Other Confidential Data If Detected" in Paste.app, as well. They recognize it's preferable to let the user decide the amount of security they need and don't force it on the user.
Hate to be a killjoy ... but I wish developers would stop trying to force security measures without ways of turning them off via a pref, for those who choose, or need this behavior. I WANT all my copied data to appear in Paste.app. And If I choose to not have that happen I can turn it off in both Enpass or Paste.app. I don't need a dev to tell me how to work safely, or force an amount of their perceived safety on the user. If need be turn on the protection by default, but give a pref to turn it off. Problem solved. And for me it is a problem—especially if 1Password has this behavior & I'm use to it.
I now own a lifetime version of Enpass. I'll be here trying to guide development, features, offer suggestions, etc, that will help Enpass be a better Mac/iOS/iPadOS app.
If this one feature alone were fixed I'd be a VERY happy camper—even though Enpass isn't a fully realized Mac app. Enpass still needs basic MacOS UI fixes, arrow keys in fields, Copy, Cut, Paste menus in the Edit menu, proper text highlight in fields in MacOS dark mode, et. al.—but this is not that discussion right now. lol
Hope this helps & does not offend.
PS ...
I tried posting this reply a few weeks ago, but the forum software kept giving me the error that I tried posting this reply too many times—on my first try & any subsequent try thereafter no matter how long I waited. Hopefully ... many days later ... it will post. ¯\_(ツ)_/¯
PPS ... Since writing this post (which thankfully I saved in Pate.app) I've switched back to Enpass and running parallel to 1Password—though I am using Enpass the most.
